Реалистичная физика токоприёмника? Ну-ну...

Освещение в Лейпциге знатно ухудшилось. Разработчики сказали, что применили вместо динамического освещения запекание ради повышения FPS, однако как раз таки на подземных станциях я никаких проблем не испытывал. В отличие от других мест.

RetroPaladin
что ж вы хотите от программистов, что делали railworks? От них же и в новый движок перетекли детские болезни.
Особенно хочу отметить один факт - UE4, на котором создана TSW, способен выдавать куда лучшую графику при бОльшей частоте кадров с просчётом физики объектов. Просто разработчики из КЫС не используют и половины его возможностей, создавая где-то избыточность, а где-то упрощают. Сейчас на мой взгляд игра всё ещё в бете и я не особо надеюсь, что она когда-нибудь выйдет из беты. Да, подтянут оптимизацию, допилят, исправят баги, но общий прогресс останется на уровне эволюции railworks просто потому что им в команде не хватает толковых программистов, которые смогут привнести что-то иное, другую реализацию кода.
Я понимаю, если бы игра создавалась вообще с нуля, но ведь они используют готовый продукт, хорошо отлаженный

Cross, а при чём здесь программисты и движок!?

эти косяки на стороне спешки и не внимательности строителей маршрута, правятся за несколько минут в редакторе :wink:

Cross писал(а):они используют готовый продукт, хорошо отлаженный

UE4 далеко не готовый и отлаженный продукт, он тоже в стадии разработки, только неделю назад вышла очередная версия Unreal Engine 4.19 с кучей доработок и исправлений!)

а теперь, внимание, про Bug Fix и Crash Fix новой версии "готового и хорошо отлаженного продукта":
[+] RELEASE NOTES
Код: Выделить всё
AI
Bug Fix: Fixed the On Perception Updated delegate to be correctly bindable to AI Perception Component.
Behavior Tree
Bug Fix: Changed the order of the Behavior Tree tick to allow Blueprint-based nodes to update before processing search data.
Bug Fix: Fixed a bug that caused a Behavior Tree asset containing a Run Dynamic Behavior node to become dirty upon opening.
Bug Fix: Fixed a Behavior Tree state change during a latent abort. Decorators and services updates are delayed until after the aborting node finishes.
New: Added the local decorator scope to the Behavior Tree Composite Nodes. The local decorator scope is controlled by the Apply Decorator Scopevariable. This addition provides better control of flow-observing decorators, allowing them to be active only in a specified branch of the tree.
New: Added a simple mechanism for logging Behavior Treenodes that reference empty or removed Blackboard keys.
Debugging Tools
New: Extended the EQS Testing Pawn with an option to specify navigation agent properties to support navigation-related EQS tests and features.
New: Added more Visual Logging functions to Blueprint.
Bug Fix: Fixed some existing Visual Logging Blueprint functions.
Navigation
Bug Fix: Fixed cases where changes to Nav Mesh Bounds Volumes properties were not causing Nav Mesh to rebuild.
Bug Fix: Fixed a failure to set the area flags when updating the Nav Area of a given Nav Mesh poly.

Crash Fix: Applied a fix for a Live Link module startup crash.
Crash Fix: Prevented threaded work from running in a single-threaded environment, which avoids a Linux server crash.
Bug Fix: Fixed debug builds hitting checkSlow when using a post process Anim Instance on a Skeletal Mesh Component without a main AnimInstance.
Bug Fix: Fixed some race conditions in Skeletal Mesh Resource Sync UV Channel Data and Static Mesh Render Data Sync UV Channel Data.
Bug Fix: Fixed a bug with adjacency DDC serialization in Skeletal Meshes.
Bug Fix: Non-rendered anim updates now run on worker threads.
Bug Fix: Changed the way Get Bone Poses For Time inside of the Animation Modifiers library retrieves the Bone Transforms for a specific time-code.

Bug Fix: Fixed pasted socket name getting an appended _0 when no other sockets contained that name.
Bug Fix: Reset Tick Records when doing 'Only Tick Montages When Not Rendered' since the montage will appear to have jumped when regular ticking resumes.
Bug Fix: URO now ensures you don't skip more frames than desired when switching LODs.
Bug Fix: Animation tasks are no longer created for Skeletal Meshes that have no anim instance.
Bug Fix: Skeletal Meshes that are not being ticked due to URO can no longer dispatch tick tasks.
Bug Fix: Fix for notifies not getting fired in cases where Always Tick Pose was set on Skeletal Mesh Components.
Bug Fix: Looping sound cues and particle systems used in notifies no longer leak a component per invocation.

New: Optimized Post Anim Evaluation when URO is skipping a frame with no interpolation.
New: Changed the notify system to allow notifies on follower animations in a sync group to be triggered.
New: Added two callbacks on Character Movement Component for the root motion world space conversion to allow users to modify the root motion:
Pre conversion (while it is still in component space).
Post conversion (when it is in world space).
New: Added Virtual Subjects to Live Link which are created within the client and contain the bones of multiple real subjects.
New: Added Initialization and Update Delta Time to Live Link Retargeter API:
Pushing skeleton to Live Link can now take source GUID.
Message bus source pushes GUID when sending skeleton.
New: Added 'Play Rate Basis' to Sequence Player node to scale Play Rate without having to do more expensive BP code.
New: Added support for Dialogue Waves driving Audio Curve Source Components.
New: Added default Get Axis Vector static function to Axis Option.
New: Skeletal Mesh Component Init Anim doesn't call Update and Eval anymore.
New: Rigid Body Anim Node Updates:
Now maintains Bone Velocity transfers through LOD changes.

Added option Transfer Bone Velocities to transfer bone velocities to simulation upon start, so ragdolls transition seamlessly from kinematic (animation) to simulation.
Added Freeze Incoming Pose On Start option to freeze incoming pose and stop ticking/evaluating rest of the AnimGraph.
New: Moved Update Component Pose Any Thread and Evaluate Component Pose Any Thread functions to Anim Node Skeletal Control Base to enable overriding these in child classes.
New: Added Pre Eval Skel Control Any Thread to Skel Control Base, to allow capture of incoming pose before SkelControl is evaluated.
New: Added the Empty function to Base Compact Pose and FCS Pose to release allocated arrays.
New: Added the notify class name to the notify tooltip.
New: Optimized redundant key removal on curves. Optimized code takes less than 1% of the time to execute of the original.

Bug Fix: Fixed Pose Asset retargeting not working for additive pose assets.
Bug Fix: Fixed issues with Pose Assets of additive blending using shortest path to blend, causing it to blend between rather than accumulating.
Bug Fix: Fixed Retarget Source for Pose Asset.
Changing Retarget Source in Pose Asset now works.
Pose Asset now saves original source pose, so that it can recalculate new pose when Retarget Source changes.
Retarget Source is used to bake the pose asset delta transform.
New: Native Animation Instances can now be set on Skeletal Mesh Components.
New: Anim Sequence Base is now entirely exported with ENGINE_API.

Bug Fix: Fixed issues where type would not be correctly propagated through multiple redirect nodes.
Bug Fix: User Defined Structures can now be imported from text using the human-readable field names, which fixes their use in nested arrays inside data table rows.
Bug Fix: User Defined Structures that are nested inside other user structs can now be safely modified. It is now safe to modify the inner struct's defaults without corrupting the outer struct, and those default changes will be correctly propagated to the outer struct.
Bug Fix: Blueprint nativization now correctly generates and builds code for "Client" builds
Bug Fix: Improvements to the Cpp backend to allow VC++ to compile nativized code more effectively

Get Scalar Parameter Value
Get Texture Parameter Value
Get Vector Parameter Value
New: Added a step to the compilation manager to skip recompilation of classes that are dependent on a given classes function signatures when those signatures have not changed. This greatly improves compile times for blueprints with large numbers of dependencies.
New: Preserve graph editor widgets when clicking on a hyperlink, this speeds up navigation via the debugger "step" command and Find in Blueprints control - both are now more responsive.
New: Added Vector Length XY to Blueprint math library.

A plugin which allows the automatic creation and configuration of in-engine data cryptography through the project settings, under the "crypto" header.
Added options to plugin settings which allow encryption to be used on the various asset files in a pak. Encryption can be used on just the .uasset file, which contains only the package header information, or the .uexp and .ubulk files too, which contain the rest of the package data. Encryption on .uasset files provides a good compromise between data security and runtime performance.
New: Added Level Streaming CVars to customize streaming for your project. These all default to enabled, but can be disabled to make different trade offs for memory and level loading performance.
"s.ForceGCAfterLevelStreamedOut" - Whether to force a GC after levels are streamed out to instantly reclaim the memory, at the cost of a hitch. Defaults to on.

New: Upgraded the Array function, Insert, to allow it to take an array with any allocator type. It can also move elements out of another Array.
New: Array now has a "_GetRef" variants for many of its functions, which will create an element and return a reference to it rather than its index in the Array. These functions are: “Insert_GetRef”, “InsertZeroed_GetRef”, “InsertDefaulted_GetRef”, “Emplace_GetRef”, “EmplaceAt_GetRef”, “Add_GetRef”, “AddZeroed_GetRef” and “AddDefaulted_GetRef”.

New: To go along with changes to the Size Map tool, the way that ResourceSize is calculated has changed. Exclusive is the same but Inclusive is now EstimatedTotal and represents the total size of the object and all of its sub objects, but not any external assets it references. It now tries to estimate the size on a generic cooked platform so it will handle texture LOD bias better.
New: The Platform Stack Walk function, Capture Stack Backtrace, now returns the stack size rather than checking for the first null pointer, to prevent truncated callstacks if parts of the stack are zeroed out.
New: Improved "caching file" message in networkplatformfile so it says "Requesting file..." and is only output when we actually request the file from the server.
New: Improved Variant's support for move semantics. Switched Variant Types over to an enum class to aid debugger visualization.
New: When cooking with Generate Chunks and the asset manager enabled, AllChunksInfo.csv is now written out to the CookMetadata directory. This file can be used to look for historical chunk size changes, and it now uses the per-platform cooked size.
New: Added more debug info for ensure in Linker Save when a name that has not yet been mapped is being serialized.
New: Tweaked "LogInit" command-line logging to clarify when the command line is incomplete due to some arguments being filtered out.

Unwind rotations from the previous transform to the current transform so that the nearest rotation is set rather than the rotator to quaternion to rotator conversion.
Bug Fix: Sequencer: Set min/max values for generic key area so that they don't default to 0,10.
Bug Fix: Fixed an issue returning unhandled only if not dragged. There was an issue where dragging in the track area would sometimes leave the handled state with the time slider controller to not allow you to pop up a menu with the movement tool.

Addresses issue if you step back to the Master Sequence (and the spawnable if it still exists) and then scrubs outside the region where the spawnable exists. It gets destroyed but saved default spawnable state doesn't get called because it's no longer the focused Sequence.
Bug Fix: Fixed Sequencer viewport invalidation so that it happens on Sequence evaluation.
Bug Fix: Fixed an issue when scrolling in track area.
Bug Fix: Fixed an issue with Sequence Recorder causing duplicate Actor triggers before playing so that the Sequence can be recorded and played back at the same time.

New: We now add a transaction for easing length.
New: Added Copy, cut, paste, and duplicate options to object bindings.
New: Added the ability to drag sections up in Sequencer.
New: Sequencer can now compile on the fly.
It is now able to compile partially or completely out-of-date evaluation templates from the source data as needed. It affords much more efficient compilation when working within Sequencer.
The concept of "instance data" for sub-Sequences, available through Movie Scene Player interface or persistent data stores. It replaces the compilation of specific templates for control rig templates.
Moved sub-tracks and sections to the Movie Scene module.
Removed the concept of shared tracks. Any previous uses should port over to shared execution tokens instead.
New: Now automatically create a camera cut track if a camera is dropped and there's no existing camera cut or there's no existing camera cut sections.
New: The sub-Sequence name is now displayed on binding ID pickers rather than sub-section name.

New: Added the ability to specify a global transform origin for Level Sequences"
It leverages the new concept of specifying an instance data object to the evaluation that allows systems to inject information into a Sequence at runtime, enabling more dynamic control of the track.
Level Sequence Actors use this by default to supply a dynamic "transform origin" to all component transform tracks, which all absolute transform sections will be added.
New: The constraint guid has been switched to constraint binding ID.
New: Playback speed has been added to the settings menu.
New: Added recording button to Sequence Recorder that adds for any selected Actors.
New: Added option to only show selected nodes only.
New: Added option to disable camera cuts on the Movie Scene Player.

New: Added default expansion states to allow track editors to specify them per track type. Material track is currently the only track that defaults to expanded.
Deprecated: We now show binding ID picker customization on all Details panels. This allows creation of new camera cut sections from existing bindings. Add New Camera Cut has been deprecated.
Removed: In Sequencer, the hotkeys Shift-C and Shift-D for toggling the Cinematic viewport have been removed. This was causing some confusion when users were accidently hitting them.
Static Mesh Editor
Crash Fix: Fixed an Editor crash when a distributed Simplygon job fails.
New: Moved the LOD sections dropdown to the LOD picker category. Custom LOD checkboxes are now hidden until "Custom" is checked. The same change applies to the Skeletal Mesh Editor.

Bug Fix: Fixed several bugs with async loading streaming levels via Streamable Manager, levels loaded this way now correctly handle offsets and navigation.
Bug Fix: Disabled the duplicate Primary Asset ID ensure for editor-only types like Maps, as it could activate unnecessarily.
Bug Fix: Exporting a Package without a type now adds warnings to the output logs.
Bug Fix: Components and Tick functions will no longer be unregistered and re-registered when testing a rename for an Actor.
Bug Fix: Modified Gameplay Tag's Import Text Item function to account for redirects when establishing Tag Name.
Bug Fix: Fixed character proxies doing up to two floor checks when only rotation is changed (there shouldn't be any). Added some optional verbose logging to the Find Floor and Compute Floor Dist functions.
Bug Fix: String allocations are no longer performed on every Server Move function call that the server runs.
Bug Fix: A bug with Post Significance not firing when unregistering an object unless it was the last object of its tag has been fixed.
Bug Fix: The engine will now only create a Material Instance Dynamic as a child of the calling object if the construction script is running. Otherwise, it will be created in the transient package.
Bug Fix: Fixed clients bypassing network move combining and RPC throttling when there is no acceleration and velocity is non-zero (for instance, when falling or decelerating). Changed velocity condition on whether moves may be combined to a delta from or to zero velocity.
Bug Fix: Fixed "infinite jump" exploits from rogue clients. The server no longer incorrectly resets the Jump Key Hold Time variable while not changing the Was Jumping variable.
Bug Fix: Log Gameplay Tags is now exposed.
Bug Fix: Disabled HLOD volume overlap events, and set to not load on client or server.
Bug Fix: Optimized client movement to avoid updating skeletal mesh bones on the client when teleporting back to combine a network move to the server. This can be avoided since the following Perform Movement call will move the mesh and cause the update there.
Bug Fix: Added stat for Force Position Update (when server ticks client that has timed out) so that it doesn't show up as Perform Movement.
Bug Fix: Redirectors or otherwise invalid .umap files are no longer considered sub levels for world composition.
Bug Fix: All Actor subclasses now correctly enforce not ticking when tick type is Viewports Only, even if they override TickActor. The Should Tick If Viewports Only function can override this by returning true.
Bug Fix: Added several transform related functions to the HIDE_ACTOR_TRANSFORM_FUNCTIONS macro and fixed the signatures on some that were already there.
New: Added a new plugin for performing data validation. Data validation can be run on individual assets, multiple assets or whole directories. It can also be run as a commandlet and included in your build process.
New: Added a function called Return To Main Menu to the Game Instance class. Games may call function to return to their main menu reliably, even in cases where a Player Controller isn't available to call Client Return To Main Menu With Text Reason.
New: Data Tables now support getting the value of each row for a specific column/property, excluding the title of the column.
New: Improved the editor UI for Primary Asset ID properties. It now uses the same one as Pins and better handles objects that aren't already loaded.

New: Added a To String to the Lex class for physics enums Collision Trace Flag, Physics Type, and Body Collision Response.
New: Added "p.NetForceClientServerMoveLossPercent" cvar to simulate loss of client-to-server movement RPCs (without hosing the rest of networking).
New: The Player Input function Massage Axis Input can now be overridden in subclasses.
New: A new variable, Should Manager Determine Type And Name, has been added to Asset Manager settings. It is disabled by default. If enabled, the Asset Manager will be able to load assets that do not have a native class that implements Get Primary Asset ID, in both the editor and a cooked game. This will behave similarly to Should Editor Guess Type And Name, but in exchange for some runtime performance it will work properly in a cooked build.
New: Primary Data Asset can now be directly blueprinted to enable blueprint-only Primary Assets, even if Should Manager Determine Type And Name is disabled. If you do this, the Primary Asset Type will be the blueprint below Primary Data Asset, which you can then inherit from to create your Primary Assets.
New: If overrides of Actor Component's Begin Play function are not routed up the hierarchy code, the engine will now use Ensure to warn that initialization steps were missed.
New: Alpha Blend struct is now marked as BlueprintType.
New: Gameplay Abilities now pass along their Source Object when creating the effect context for a new effect.
Consolidated all of the events on Active Gameplay Effect into a single struct.
New: Added an active effect event for when the inhibition of an effect changes, meaning that the effect is no longer relevant, but had not actually been removed.
New: Added functionality to cycle between targets with Page Up and Page Down for 'showdebug' commands. List of targets is contextual (For example 'showdebug animation' will consider all visible actors with an AnimGraph). Current debug Target is highlighted in a green bounding box.
New: Performance optimization: Added Network Skip Proxy Prediction On Net Update to the Character Movement Component. This skips immediate forward prediction for proxies on the frame they receive a network update, avoiding all forward prediction sweeps and floor checks on those updates. Intermediate frames will interpolate with prediction. This can also be disabled globally by setting the CVar "p.NetEnableSkipProxyPredictionOnNetUpdate" to 0.
New: Reduced overhead of evaluating streaming level volumes when all Player Controllers have Is Using Streaming Volumes set to false.
New: Significance Manager's Update function now takes viewpoints in as an Array View instead of a const Array reference.
New: When keys with unknown character code are received by the input system, a new Key struct will now be dynamically created to represent it rather than it being rejected as an invalid key.
New: Significance Managers' Post Significance Update functions can now specify to be executed sequentially on the game thread instead of only as concurrently in the parallel for.
New: Conditional Init Axis Properties is now protected instead of private, so it can be seen by child classes.
New: The Smooth Mouse function is virtual, so games can implement their own smoothing code.
New: Added Rand Point In Circle function. It returns a random point, uniformly distributed, within the specified radius.
New: Updated ensures to give more information when there is an invalid Ground Movement Mode.
New: Added a new trait called Post Script Construct. This enables users to perform initialization after blueprints have created a temporary object.

RemovedTool directly, rather than using the Automation Tool Launcher.
Bug Fix: Fixed one CPU core spinning during compilation using Parallel Executor. This was due to Completed Event never being reset.
Bug Fix: Fixed the ability to distribute app-local dependencies with games packaged using the launcher UE4 distribution.
Bug Fix: App-local dependencies now work for C++ and Blueprint projects.
Bug Fix: Fixed a race condition where stdout/stderr write handles could be inherited by multiple processes, resulting in them not being closed (and the process exit being detected) until all processes that inherited them had been closed. This improves performance of Parallel Executor.
New: Added support for external projects with new parameter to "List Third Party Software". The parameter -ProjectPath specifies the path to the UProject file so that the build rules of the project are parsed and the folder is part of the search for Third Party Software files.
New: Lowered logging level for cached file notification during Cook from Warning to Verbose in order to reduce clutter in the logs.
Removed: Code that deletes cooked data on a failed cook has been removed because deleting the cooked data prevented post-mortem analysis. The Engine now writes out packages transactionally by writing to a temporary file and moving them into place.
Removed: Code that executes pre-built steps from UE4Build have been removed. These build steps should be executed before generating the action graph. So, they have to be done inside of Unreal Build Tool. Running them here causes them to execute twice.

New: Added include and library-related fields to module JSON output.
New: VSWHERE is now used to find the location of MsBuild.exe if available.
New: Improved error handling while generating intellisense project files. It now includes the name of the target being compiled and allows project file generation to continue without it.
New: The Module Rules "Definitions" property has been renamed to "Public Definitions", to make its semantics clearer. A complementary "Private Definitions" property has also been added.
New: UnrealBuildTool now validates that targets don't modify properties that affect other targets. For example, modifying global definitions for an Editor target, where other Editor targets may use the same engine DLLs).
New: Added the build version to the Target Rules and Read Only Target Rules class, allowing it to be read from the target and module rules files.
Changed Launch.build.cs to set private defines for the build changelist in non-formal builds. This allows the version to be set correctly with executables copies to console.
Modular builds on desktop platforms still read the Version file from disk since it's quicker than compiling a value in. They need the build ID to prevent mismatched binaries.
New: Version files are only generated for non-promoted builds, and are included in the target receipt.
New: Added a proper error message if the user attempts to clean a target through hot-reload, rather than just failing to delete DLLs because they are locked.
New: Added a logging option to format output messages in a form that can be parsed by MSBuild. This prevents errors showing as "EXEC: Error:", and displays them correctly in the error list window.
New: Unreal Build Tool will now use the preferred source code accessor selected in the editor to compile with, if an explicit compiler is not specified in the Project Settings.
Deprecated: Unified command line arguments now use the -Name=Value syntax. The following are no longer supported:
-Module <Name>
-ModuleWithSuffix <Name> <Suffix>
-Plugin <Path>
-Receipt <Path>
Removed: UDN documentation source files are no longer included in the generated project files by default.
UnrealGameSync
Bug Fix: Fixed an issue so that the project filename is now included in the Editor build command. The project may not be in one of the .uprojectdirs paths.
Bug Fix: Fixed an issue where the "More Info..." button was not using P4 server override.
New: UProject and UPlugin files are now treated as code changes. This change was made since they can invalidate the Editor target.

UnrealVS
New: Added Log GenerateProjectFiles to file when using Unreal VS.
UI
Crash Fix: Fixed a line-ending inconsistency when retrieving rich-text that could cause Input Method crashes.
Bug Fix: Fixed some clipping issues that could occur with right-aligned text.

This is enabled by default, and can be disabled by setting Should Use Localized Numeric Input to False in the XEditorSettings.ini (for the editor), or XGameUserSettings.ini (for a game).
New: Added support for a catch-all fallback font within composite fonts.
This allows you to provide broad "font of last resort" behavior on a per-composite font basis, in a way that can also work with different font styles.
New: Added support for per-culture sub-fonts within a composite font.
This allows you to do things like create a Japanese specific Han sub-font to override the Han characters used in a CJK font.
New: Safe Area is no longer centered or symmetrical. The UI will use the Safe Area reported by the OS.
New: Added Editable Text functionality.
Slate
Crash Fix: Fixed a crash when trying to use the widget reflector in a client cooked build.
Bug Fix: Fix for accessing Slate window on render thread.

Bug Fix: Fix slate material box brushes not being keyed off image size.
Bug Fix: Added conditional to only unregister the active timer if it is still valid after execution.
New: Slate now supports a Custom Boundary Navigation type which allows a custom handler if the boundary is hit.
This provides the ability to have normal navigation while within the boundary and the custom function only on the boundary.
This differs from Custom, which is a full override of the navigation behavior.
UMG
Crash Fix: Fixed a crash on compile due to partial GC of a widget.
Crash Fix: Implemented a fix for a crash when playing in editor after changing, but not compiling, a Widget Blueprint.
Crash Fix: Calling Find All Ancestor Named Slot Host Widgets For Content with a null widget no longer crashes.

Bug Fix: Fixed paused state so that it doesn't return widgets to their original state.
Bug Fix: UMG objects returned from Create Widget and Create Drag Drop Operation are no longer marked as always being hard referenced by the blueprint.
This means that they will no longer leak if they are not in use.
If the widget or drag operation are on screen they will correctly stay in memory, but if you need them not to be freed for other reasons, you can assign them to a blueprint variable.
Bug Fix: Fixed Additive UI materials not being affected by the widget opacity.
Bug Fix: Common Activatable Panel does a better job of cleaning up when it is reset.
Bug Fix: Common Tree View Set Selection correctly updates list navigation and behaves similarly to Common List View Set Selected Item.

New: Added an option to Motion Controller components to display an optional model (see the Display Device Model option in the component's details). This can be set up to generically use the device model provided by the backing XR system (if the system has one).
New: Added new Blueprint functions to generically enumerate tracked devices, and another to request a model component from the backing XR system (NOTE: at the moment, not all systems support returning a model).
New: Added a "MotionDelayBuffer" service to the engine that hooks into Motion Controller components, and lets programmers render the components at a delayed rate (to simulate latency).
New: The XR Tracking System and Head Mounted Display interfaces have been updated to make handling of pose updates and late update more explicit.
New: Added a new function to convert poses from XR tracking space to Unreal world space.
New: Changed Motion Controller "Hand" property to a more generic “MotionSource” name field, and added a function to query for generic float parameters associated with the Motion Controller.
New: Added new Blueprint node for getting the current VR pixel density.
New: Refactored the Rift dynamic resolution implementation to use the new general Dynamic Resolution State interface.
Deprecated: XR Tracking System interface function Refresh Poses has been deprecated.


UPGRADE NOTES
Animation
Animation Blueprints
Bug Fix: We changed the order of how to get the material default value. Previous implementation was to get parent's default value first before itself, which was incorrect, so we fixed it by getting own default value if exists. However, if you were relying on the previous behavior, you're going to see the issue. Make sure you set correct default value for the material instance if it was incorrect.
Bug Fix: If this code executes (it will add a log warning if it does) it could cause problems with deterministic cooking / patch creation as new guids will be generated during cook. Nothing will break but patch sizes could be bigger than they need to be. Re-saving the problematic assets will correct the issue.
Skeletal Mesh
The function name of SkeletalMeshComponent::PostBlendPhysics() has changed to FinalizeAnimationUpdate() for clarification.
Blueprints
New: Step Into has been remapped to the F11 key. The Step Over command is now mapped to F10 instead.
User Defined Structure default values now correctly propagate to blueprints and other user structs the same way that native structs do, which may cause issues if your blueprints were depending on this not happening. If this is a problem you may need to modify your outer blueprint or struct and set some values back to empty or 0.
Core
VisitTupleElements has had its parameters swapped - the visitor is now the first parameter, followed by the tuple (now multiple tuples). Any existing calls will need to swap arguments.
FPlatformAtomics::AtomicRead64() has been deprecated - the int64* overload of FPlatformAtomics::AtomicRead() should be used instead.
The bWasReloaded flag was removed from FModuleManager::LoadModule(), FModuleManager::LoadModuleChecked() and FModuleManager::LoadModuleWithFailureReason() - any calls to it should also remove this flag.
TWeakObjectPtr's constructor was silently casting away const - this has now been fixed and any use of TWeakObjectPtr will now warn if it is not const-correct.
UE4 containers now expect move-aware allocators, which means they need to support the MoveToEmpty(SrcAllocator) member function to move all elements across from SrcAllocator, leaving it empty. Any custom allocators should be updated to add this support and specialize the TAllocatorTraits<Allocator>::SupportsMove trait to be true.
FArchive::Logf() and checkf() macros will now fail to compile if they are not passed a literal formatting string - these should be fixed to use a formatting string like TEXT("%s").
If you have any build scripts that were looking for DevelopmentAssetRegistry.bin or other metadata files you will need to change them to look inside the new Metadata directory.
Code using PLATFORM_COMPILER_HAS_DEFAULTED_FUNCTIONS or PLATFORM_COMPILER_HAS_AUTO_RETURN_TYPES should be replaced with the assumption they are always 1.
ENamedThreads::RenderThread and ENamedThreads::RenderThread_Local are no longer publicly accessible - they should be replaced with ENamedThreads::GetRenderThread() and ENamedThreads::GetRenderThread_Local() respectively.
TVariant::GetType() now returns an EVariantTypes enum class instead of an int32. Any use of this return value as an int32 will need to be changed to EVariantTypes.
Bug Fix: PPF_DeltaComparison has been removed - please remove any use of it from your projects.
Bug Fix: Calls to Align(), AlignDown(), AlignArbitrary() and IsAligned() will no longer compile if passed a non-integer/pointer type. This often fires when trying to align an enum value - it should be explicitly cast to an integer type of the right size.
Bug Fix: Calling FReferenceCollector::AddReferencedObjects() with a container will no longer compile if the container has pointers to forward declared types. You should ensure the types are included before calling this function.
Editor
The debug canvas for stats is always dpi scaled in editor and pie. Any existing tools that directly use viewport positions and size as positions for canvas elements will need to divide out dpi scale using 1/CanvasObject->GetDPIScale().
Bug Fix: Note: This only applies to perforce users NOT using ticket based perforce servers.

The perforce source control login flow will no longer make any calls to the perforce api which results in a password being stored on the local users machine by perforce. We have determined that the security level of this feature is not high enough to continue using it. Users can now expect to have to type in their perforce password each time they open the editor. To work around this users can call p4 passwd directly from a command window to save a password on their machine if they so choose.

Sequencer
'Shared' templates are no longer supported in sequencer. Any previous usage should be easily converted to a shared execution token instead (FMovieSceneExecutionTokens::AddShared()). Such tokens are shared globally, rather than per sub-sequence which makes them more robust for shared responsibilities.
Gameplay Framework
Bug Fix: AActor subclasses that intended to be tick when the tick type is Viewports Only and did not set ShouldTickIfViewportsOnly to return true, but instead overrode TickActor and did not filter on Viewports Only will now need to correctly implement the ShouldTickIfViewportsOnly virtual to achieve this behavior.
Networking
UNetConnection::ClientWorldPackageName is now a private member and should accessed through the available Get/Set methods.
Bug Fix: The net.UseAdaptiveNetUpdateFrequency console variable is now disabled by default, since it was causing replication issues in many projects. If you want to keep using this feature, you may enable it in your project's configuration files.
Rendering
We changed the Vertexbuffer layout from AoS to SoA because after this change we can bind the Input Attributes via SRV and load them in the shader directly (also from compute). Before this change it was very difficult and involved manual interpretation of the Raw Data in the Shader. We recommend everyone to follow this route and change their Vertexbuffers as we probably will deprecate mixed AoS Vertexbuffers in the Future.
Tube shaped point lights will be automatically rotated to compensate for this change. Dynamically generated point lights with a source length will need to have a 90 degrees pitch added to their orientation.
Inside Sequencer->Render->CompositionGraphOptions
Set Output Format to "Custom Render Passes"
Set Include Render Passes to "Final Image"
Set Capture Frames in HDR "On"
Set Capture Gamut to "Linear"
UI
UMG
Bug Fix: If a game was depending on this functionality to keep things loaded, change your blueprint to set the return value into a variable, that will keep it hard referenced normally
VR
VR Screen Percentage has been refactored to support new upsample and Dynamic Resolution rendering features. See this post for more details about these changes.
XR
Deprecated the MotionController component's EControllerHand 'Hand' property and replaced it with a 'MotionSource' name. To support the same functionality, use names corresponding to the old enum values ("Left", "Right", etc.).
vr.oculus.PixelDensity.adaptive has been removed. Dynamic resolution needs to be enabled using the general engine system now.


PROGRAMMING UPGRADE NOTES
AI
Bug Fix: Fixed a bug in UAISense_Sight::UnregisterSource that resulted in sources being removed not getting removed from the ObservedTargets collection.
Debugging Tools
Redone how visual log is using categories. Now it's using FName rather than FLogCategoryBase to indicated log category. All UE_VLOG macros have been updated. This change made it possible to actually vislog things using blueprint functions.
Navigation
Bug Fix: Fixed navmesh not loading properly in PIE when owning world has been duplicated-for-play
Animation
Bug Fix: Now when meshes are set to EMeshComponentUpdateFlag::AlwaysTickPose, we optionally kick of a task to perform parallel update only (no evaluation). Previously we needed to run this on the game thread as if we skipped evaluation we did not run a worker task.
Audio
New: The new Microphone Capture Component enables feeding audio directly into a game for use with the Audio Engine and for driving in-game parameters. Limitations:
Only implemented on PC.
Only for local client microphone capture, not connected to VoIP system.
Doesn't support recording microphone output to assets.
Automation
Added automated test per-platform blacklist, defined in the project DefaultEngine.ini or platform equivalent e.g. MacEngine.ini:

[AutomationTestBlacklist]
;Use format +BlacklistTest=(Map=/Game/Tests/MapName, Test=TestName)
+BlacklistTest=(Map=/Game/Tests/Physics/Stability, Test=StackCubes)
Automated test screenshots are now able to test against a hierarchical fallback platform and RHI. This is defined in DefaultEngine.ini, for example:

[AutomationTestFallbackHierarchy]
;Use format +FallbackPlatform=(Child=/Platform/RHI, Parent=/Platform/RHI)
+FallbackPlatform=(Child=/Windows/OpenGL_SM4, Parent=/Windows/D3D11_SM5)
+FallbackPlatform=(Child=/Mac/SM5, Parent=/Windows/D3D11_SM5)
Core
Any usage of FStartupPackages in project code should be removed
"Native" (now called “FNativeFuncPtr”) is now a function pointer that takes a UObject* context, rather than a UObject member function pointer. Use “P_THIS” if you were previously using the “this” pointer in your native function.
FTickableBaseObject::GetTickableType can be overriden and returns an enum value of either Conditional (default), Always, or Never.
Tickable Never objects will not get added to the tickable array or ever evaluated.
Tickable Always objects do not call IsTickable and assume it will return true.
Tickable Conditional objects work as in the past with IsTickable called each frame to make the determination whether to call Tick or not.
FTickableObjectBase::IsTickable() is no longer a pure virtual.
To match the change in functionality EResourceSizeMode::Inclusive was changed to EstimatedTotal. If any of your code was using Inclusive, you need to decide whether you want to change to EstimatedTotal or Exclusive.
The ResourceSize asset registry tag has been removed as it was inaccurate. To get an accurate estimate, you must load the object and call GetResourceSize().
Bug Fix: Cleaned up delegate definitions in UObjectGlobals.h and moved several to be WITH_EDITOR. If you were using those definitions in a game you will need to wrap your use in WITH_EDITOR.
Editor
Being an early feature, some Editor UI buttons do not work during playback of demos.
The debug canvas for stats is always dpi scaled in editor and pie. Any existing tools that directly use viewport positions and size as positions for canvas elements will need to divide out DPI scale using 1/CanvasObject->GetDPIScale().
RenameAssetsWithDialog() is often recommended in places where RenameAssets() was being used.
The SizeMap and ReferenceViewer have been merged into the AssetManagerEditor plugin so they can share the data needed to show cooked sizes.
Gameplay Framework
C++ Header cleanups for Actor, Pawn, Character, Controller, and PlayerController. Marked several fields as private that were accidentally exposed in 4.17.
Projects using this plugin are strongly encouraged to add a project specific subclass of UDataValidationManager. Any objects that require validation should override IsDataValid.
Overriden versions of USignificanceManager::Update will need to change signature to receive a TArrayView instead of const TArray&amp;.
Networking
Bug Fix: Programmers using HasPendingConnection() on a listening FScocket should consider using the new WaitForPendingConnection() function instead, which prevents wasting CPU cycles due to polling. This change supported a change to the behavior of the FTcpListener constructor's InSleepTime parameter which now specifies the maximum time to wait for a connection in its polling loop. It now defaults to 1 second, but using a value of 0 will restore the previous polling behavior.
Online
This Online Presence Test requires that the testing user to have friends and be connected to the platform.
Usage is "online test presence [OPTIONAL ID]". The ID passed should be an arbitrary non-friend. If no ID is passed, the arbitrary lookup test is skipped. This test does wait for presence updates for about two minutes, after this time if no updates are received, the harness will mark the test as a failure.
Rendering
The STRONG_TYPE #define now seen in UE4 .usf/HLSL is actually hlslcc's "invariant" keyword applied as a type-qualifier to a Buffer&lt;>/RWBuffer&lt;> type - only valid when using Metal which exports this through ILanguageSpec and #define'd out for everyone else. When this is applied the MetalBackend will emit a "raw" buffer whose type must match the shader exactly, which avoids the overheads of Linear-Textures &amp; Function-Constants.
Vertexbuffer Objects now bind their SRVs directly instead of filling out a StreamDescriptor. Care must be taken when the Vertexfactory is initialized before the VertexBuffer as the bound SRV will become invalid if the underlying vertexbuffer is re-created. We do not support late binding of the data anymore.
Mobile Rendering
Removed cvar "r.AllReceiveDynamicCSM" and primitive flag “FPrimitiveSceneProxy.bReceiveCombinedCSMAndStaticShadowsFromStationaryLights”. Added “FPrimitiveSceneProxy.bReceiveMobileCSMShadows”, which now applies to both stationary and movable lights and defaults to on.
Tools
UEdGraphPin::PinCategory, UEdGraphPin::PinSubcategory, and UEdGraphPin::PinName are now stored as FName instead of FString.
UEdGraphPin::CreatePin has several simplified overrides so you can only specify Subcategory or SubcategoryObject or neither.
UEdGraphPin::CreatePin also takes a parameter bundle for reference, const, container type, index, and value terminal type rather than a long list of default parameters.
Material Expressions now store input and output names as FName instead of FString.
FNiagaraParameterHandle now stores the parameter handle, namespace, and name as FName instead of FString.
Most existing pin related functions using string have been deprecated.
UI
Slate
Renamed FTextBlockLayout to FSlateTextBlockLayout to reflect that it's a Slate specific type
XR
If you maintain a VR or AR plugin, you will have to remove your RefreshPoses() override and move any late update functionality to OnBeginRendering_RenderThread/GameThread(). Alternatively, if your plugin does not support late update, you can remove RefreshPoses() completely and override DoesSupportLateUpdate(), returning false.
Added two methods to the IXRTrackingSystem API - GetTrackingToWorldTransform() and UpdateTrackingToWorldTransform(). GetTrackingToWorldTransform() is expected to return an transform that will convert poses from GetCurrentPose() into world space. UpdateTrackingToWorldTransform() is meant for users to override the transform since the anchor between the two spaces is controlled by the project.
MotionControllerComponents' 'Hand' property is no longer available. Instead, switch to using the new 'MotionSource' field with text names matching the old enum values ("Left", "Right", etc.). For ease of use, "Left" and "Right" are predefined in FXRMotionControllerBase (as LeftHandSourceId &amp; RightHandSourceId).
Replaced EControllerHand parameters in the IMotionController API with generic "source" name parameters. To handle backwards compatibility, use name values corresponding to the old enum ("Left", "Right", etc.).
Added two new functions to the IMotionController API - EnumerateSources() &amp; GetCustomParameterValue(). Use EnumerateSources() to return a list of the supported devices (replaces the static EControllerHand enum). GetCustomParameterValue() can be used to expose float values associated with the motion device (such as FOV with cameras, etc.).
VR
The GetHMDDistortionEnabled method on IHeadMountedDisplay how takes a single argument of type EShaderPath. If you maintain a custom HMD plugin, you will need to update your method signature.
DEPRECATIONS
Automation
UFunctionalTestingManager::RunAllFunctionalTests has dropped an unused parameter. The original version is now deprecated.
Core
Removed the PLATFORM_HAS_64BIT_ATOMICS macro, as it is always 1.
Deprecated the VARARG macros and replaced them with variadic templates.
Editor and Tools
Deprecated Material Baking functionality inside of the MaterialUtilities module. Users should use the functionality provided by the Material Baking module instead.
Gameplay Framework
Add APlayerController::ClientReturnToMainMenuWithTextReason to support an FText reason parameter so that the message can be localized. Deprecated APlayerController::ClientReturnToMainMenu.
Rendering
The Editor is now only supported on Feature Level 5 platforms. Feature Level 4 platforms (D3D10, OpenGL3) are no longer supported.
Materials
Material Layer experimental support feature, Shared Input Collection and associated material graph nodes have been removed. See the forum feedback thread for more insight.
Tools
UnrealBuildTool
The bOutputToEngineBinaries flag has been removed from the target rules. The output directory for targets is always determined by the location of that target.
XR
The IHeadMountedDisplay::GetHMDDeviceType() method has been removed as it was not extensible enough. Code that needs know which XR plugin is currently active should use IXRTrackingSystem::GetSystemName() instead.

те же артефакты Motion Blur как раз проблемы UE4, на которые жаловались многие разработчики, и Epic Games намерены в будущем исправить это!)

та и не стоит сравнивать UE3.5 и UE4, так как UE4 это задел на будущее для современных и более новых технологий :)

проблемы с ним не только у DTG, но и более раскрученных компаний, хотя, DTG и не скрывают, что они новички в этом деле и на этапе разработки изучают UE4 :beer:

whity, то есть UE4 готовый и отлаженный продукт, а все Bug Fixes и Crash Fixes это вымысел Epic Games!? в чём конкретно я не прав!?

по этой ссылке Unreal Engine 4.19 Released как раз приведены нововведения, bug fixes, сrash fixes, и не стоит это всё смешивать в одну кучу, это разные действия :wink:

двойные стандарты, ты соглашаешься, что UE4 готовый продукт, хорошо отлаженный, а TSW всё ещё в бете, когда на самом деле оба продукта в стадии разработки и развития с улучшениями и исправлениями, при этом второй из них зависит от первого :shock:

animalkosmik
разница между разработкой и патчами для готового продукта всё же есть. Разработка, это создание базовых функций с постепенным расширением функционала, чтобы на выходе получился уже готовый продукт. Этот самый готовый продукт затем и шлифуют, так как на стадии разработки нельзя отловить все баги. К тому же в обновлениях движка правятся не только косяки, но и добавляется новый функционал.
Если я изначально не так выразился и вы не поняли о чём я пишу, то прошу меня извинить. Собственно эту разницу я имел в виду.
UE4 готов и его постепенно улучшают.
В случае с TSW немного повторюсь с внесением ясности в мысль - программисты и движок взаимосвязаны тем, что приходится адаптировать свои наработки и интегрировать функции движка для того, чтобы мы с вами и увидели эту самую игру. К тому же программирование осуществляется на разных уровнях, как написание скриптов для локомотивов, светофорной сигнализации и прочее, так и программирование шейдеров (UE4 это поддерживает, в нём можно создавать собственные шейдеры), рискну предположить, что DTG создали ещё и правила путей на манер railworks, ибо иначе я не могу объяснить формирование стрелочных переводов с расстановкой механизма переключения, упирающегося в соседнее полотно. Ну и конечно же соглашусь - спешка, сроки, не уделяют должного внимания аспектам геймплея, элементарных ошибок в сценариях и другие прелести.

Cross, тогда и TSW готов и его постепенно улучшают :)

Обновление Train Sim World от 20.03.2018
ОСНОВНОЕ
Система Пассажиров:
-Теперь на платформах пассажиры будут появляться в радиусе 1 километра от игрока
-Переделана навигационная карта искусственного интеллекта пассажиров на всех станциях, теперь они не будут ходить ровной колонной на станциях
-Переставлены точки появления пассажиров, чтобы они могли быстрее добраться до нужной им платформы
-Теперь пассажиры заранее знают, когда и на какую платформу прибывают поезда на определённой станции, поэтому они будут стремиться попасть на платформу, на которую скоро прибудет поезд, и будут уходить с тех, на которых его ещё долго не будет
-Увеличена частота появления пассажиров на станциях для общего увеличения объёма пассажиропотока
-Добавлен чёткий лимит максимального количества пассажиров на станции, чтобы избежать падения производительности
-Скорректирована система появления пассажиров, теперь они будут «выходить» из разных точек на платформе, а не только из одной
-Многочисленные изменения в системе посадки/высадки пассажиров

Вылеты Игры:
-Исправлены вылеты игры при попытке загрузить недостающие вагоны/составы

Геймплей:
-Исправлено неверное направление установки вагонов, появляющихся в «порталах»
-Исправлена ошибка, из-за которой в диалоговых окнах отображалось техническое внутриигровое название состава вместо номера модели
-Исправлена ошибка при построении маршрута, если длина состава меньше, чем та, которая указана во внутриигровых инструкциях на сцепку/расцепку
-Разрешено «ручное» планирование точек назначения отцепов для неявных случаев, где сложно найти верные (в качестве временной меры)
-Исправлена ошибка при построении маршрута, если локомотив резко менял направление движения сразу после сцепки/расцепки вагонов
-Улучшена система построения маршрута с точки зрения безопасности
-Маркер сцепки/расцепки теперь показывается над конкретной автосцепкой, а не в середине вагона
-Теперь отображается число вагонов, которые должны быть прицеплены или отцеплены, а также общее имя каждой группы вагонов
-Исправлена ошибка, из-за которой сигнализация продолжала срабатывать, даже если был выключен соответствующий предохранитель
-Изменена чувствительность геймпада при управлении внутриигровой путевой картой
-Исправлена ошибка, из-за которой нажатая ранее кнопка застревала в нажатом положении после сохранения/загрузки
-Внешняя камера ('2') теперь не сталкивается с грузом в вагонах

ДОПОЛНЕНИЕ GP40-2
-Добавлена окраска YN3b для локомотива
-Исправлены линзы задних буферных огней на локомотиве
-Изменён внешний вид номерных табличек, отключённых сигнальных огней, выхлопных решёток для обеих окрасок

ДОПОЛНЕНИЕ RAPID TRANSIT
Игровой Мир:
-Полностью изменено освещение для подземной части линии с динамического на запечённое статическое, что должно положительно сказаться на производительности и визуальной составляющей игры
-Полностью переработано освещение туннелей и подземных станций для корректной работы с подвижными объектами, такими как: пассажиры, железнодорожные составы и так далее
-Исправлена ошибка, из-за которой на некоторых станциях у пассажиров отсутствовала инструкция посадки/высадки из вагона
-Исправлены маркеры платформ на Dessau Hbf, исправлено поведение пассажиров на станции
-Переделана навигационная карта искусственного интеллекта пассажиров на станции Bitterfield, теперь они не проваливаются под платформу
-Исправлена коллизия в туннелях в подземной части линии
-Исправлена коллизия лестницы на станции Leipzig HBF
-Исправлены участки, на которых отсутствовала контактная сеть

Bombardier Talent 2 (BR 442):
-Исправлено поведение пассажиров внутри состава, теперь они выбирают корректную сторону при выходе из вагона

ДОПОЛНЕНИЕ GREAT WESTERN EXPRESS
High Speed Train (Class 43):
-Изменены LOD'ы (уровни детализации) сидений в поезде, что положительно скажется на производительности

Class 166:
-Исправлена коллизия между пассажирами и дверьми

TSW остаётся пробником с множеством нереализованных идей, и те патчи, которые сейчас выходят, охватывают несколько дополнений и тот маленький кусочек, именуемый ядром игры (что успели наработать). TSW ещё не выходил из беты. Тем более, что в игре ещё нет обещанного редактора. Так что это явно не готовый продукт

Cross, UE4 тоже не готовый продукт, UE3.5 готовый, но явно не UE4!)

какой из них готов!? я уж промолчу про кучу Bug Fixes и Crash Fixes в каждой версии, и по несколько Hot Fixes на некоторые версии :)
Update 4.1 is live!
Unreal Engine 4.2 Update
Unreal Engine 4.3 Released!
Unreal Engine 4.4 Released!
Unreal Engine 4.5 Released!
Unreal Engine 4.6 Released!
Unreal Engine 4.7 Released!
Unreal Engine 4.8 Released!
Unreal Engine 4.9 Released!
Unreal Engine 4.10 Released!
Unreal Engine 4.11 Released!
Unreal Engine 4.12 Released!
Unreal Engine 4.13 Released!
Unreal Engine 4.14 Released!
Unreal Engine 4.15 Released!
Unreal Engine 4.16 Released!
Unreal Engine 4.17 Released!
Unreal Engine 4.18 Released!
Unreal Engine 4.19 Released!

сейчас TSW на 4.16, TSW beta была на 4.15, и многие исправления, которые коснулись TSW, как раз и были исправления в версии движка 4.16, и многие будущие исправления, например Motion Blur, будут на уровне движка, а не так, как ты говоришь, что DTG не хочет!)

и о какой готовности UE4 можно говорить, когда в каждой новой версии мы получаем не только нововведения, новые инструменты и функционал, исправления ошибок и тому подобное, но и экспериментальные функции, которые будут доработаны в следующих версиях!)

то есть, то что мы сможем делать в готовом UE4.19, мы не сможем сделать в готовом UE4.18, уже не говоря про готовый UE4.1!)

например, нам нужная система LODирования ландшафта несколько раз уже переделывалась Epic Games, и в последней версии 4.19, которая вышла 14 марта, она опять переделана, и при этом ещё добавлено управление тесселяцией!)

точно также и TSW, в каждом билде мы получаем нововведения и функционал с иправлением ошибок и так далее, для GWE необходима была система пассажиров, для RT коллизия токоприёмника, также уже написан код для реализации PIS (Passenger Information System) :good:

если проводить параллели, то нет разницы между "готовым продуктом" UE4 и "бета" TSW :pardon:

хорошо, отделим мух от котлет. UE, это самостоятельный движок, у которого свои разработчики, своё развитие, свои баги, доработки, выходящие в патчах и т.д.
TSW, это игра, которая основана на UE4 и черпает из него ресурсы, что нам и даёт то, что имеем в нынешнем виде. Хочу особо отметить то, что это разные вещи - самостоятельный движок и игра, берущая ресурсы из этого движка.
Сборки, выходящие для UE4 просто дополняют его и попутно исправляют ошибки прошлых версий, но основа уже была заложена, когда появился этот самый UE4 после 3.5. Можно создать какой-либо инструмент, который привнесёт новые возможности и поможет создавать те вещи, которые раньше не представлялись возможными без него, а можно дорабатывать уже имеющийся инструмент, оптимизировать его алгоритм работы, добавлять что-то в логику и исправлять попутно ошибки. Чувствуешь разницу?
А вот TSW на текущий момент сама по себе "голая" и не обладает какими-либо инструментами для создания собственных сценариев, собственных маршрутов, возможно чего-то ещё, что расширит возможности. Разработчики пока только обещали создать редактор, но когда он будет, это хороший вопрос. Ну и сам по себе TSW появился не так давно, если рассматривать его как отдельный от UE4 продукт.
Честно говоря не знаю как точнее описать разницу между готовым решением и дорабатыванием готового решения, чтобы это было предельно понятно :roll:

Cross, я именно и рассматривал их как отдельные продукты :shock:

то что ты написал про UE4, также относится и к TSW, ведь TSW тоже уже имеет основу, и все билды просто дополняют её и исправляют ошибки прошлых версий :wink:

Cross писал(а):А вот TSW на текущий момент сама по себе "голая" и не обладает какими-либо инструментами для создания собственных сценариев, собственных маршрутов

ну так игровой движок изначально задуман так, в общем смысле, как редактор с инструментами, в отличии от игры!)

большинство игр не владеют инструментами для создания контента, но это не значит, что они бета не готовые, тем более DTG делают собственные маршруты и сценарии :)

именно поэтому UE4 как игровой движок и TSW как игра в стадии разработки и развития с улучшениями и исправлениями, в отличии от UE1/2/3 и RS/RW/TS!)

за другие игры говорить не будем, речь о TSW в рамках данной темы. Вот никак я не могу её считать полноценной даже с выпущенными дополнениями, ибо сценариев практически нет, наполненности по геймплею никакой, мир абсолютно пустой, физика весьма посредственная. Появилась фишка с гуляющим машинистом, но это больше похоже на технологическую демку, чем на полноценную игру. Красивая графика (хорошо, получше, чем в классической railworks) ещё не говорит о достижениях разработчиков TSW, графику выдаёт UE. Да в игре даже небо стандартное движковое. Я не нахожу в TSW полноценно проработанных элементов, но наблюдаю в разных аспектах сплошные начала. Это не стадия улучшений, это новая неспешная разработка и адаптация под новый движок.
Так что с точки зрения игры ещё очень много предстоит сделать, чтобы можно было считать её доделанной. Вся эта бета складывается из таких вот нюансов - там не сделали, тут оставили на потом, ещё что-то где-то пока и так сойдёт

Прошу прощения, но Вы забываете про самое фундаментальное:
- маршрут с объектами, локомотивы, вагоны
Это огромная куча ценной работы!

Именно за это вы платите 600 рублей (300 со скидкой)!

Графика только преподносит это в лучшем (как может выдать движок) виде. Считайте - для вас это бесплатно.

Ошибки? А что сейчас делается в МИРЕ без ошибок?

Cross, ты же шаришь в скриптах.
Если бы ты создал один из ниже приведённых локов в статусе "РЕЛИЗ", какую цену ты бы за него с нас запросил?

разве не прогресс!?

ага, UE и сам определяет, как ему освещать, определяет типа материалы, где металл, а где другое, и сам всё угадывает и настраивает ну и всё такое!?

вот какую графику выдаёт UE4:

DTG не Ubisoft, и у них нет студий по всей планете, чтобы разрабатывать круглосуточно :)

Moss®
в скриптах лучше шарит Света, это я особенно хочу выделить :)
Мне сложно говорить о цене, опираясь только на работу со скриптами. До этого проделывается куча всякой рутинной работы по подготовке и моделированию, текстурные развёртки, создание текстур, анимации, звуки... Нет, я не списываю со счетов труды разработчиков никоим образом. Но вам, как самому обыкновенному пользователю, хочется видеть не только красивую картинку, но и интересный, наполненный событиями игровой мир. Чтобы это всё создать, требуется целая команда людей, очень много времени на реализацию идеи. Я всего лишь хочу сказать, что игра далека от финальной задумки и находится в активном процессе разработки, являясь пока что бетой. Новый движок привносит уйму возможностей для разрабов и эти возможности по-чуть реализуют патч за патчем. Это не только оптимизация и повышение fps, это работа над картинкой (шейдерное программирование и освещение), это всевозможные адаптации, связки, это и детализация объектов, сюда можно очень много добавить.
Railworks тоже развивался не сразу, а я очень хорошо помню игру 2010 года, именно тогда я начал проявлять интерес к подобным симуляторам. С тех пор случилось много преобразований и в конце мы дошли до исчерпывающих возможностей kuju движка, далее у разрабов нет смысла возиться с этим движком. Сейчас наблюдается та же тенденция разработки, но с одним отличием - потенциала на будущее больше, но не в ближайшее время

знать бы, что там у них за "финальная задумка"
если движок развивается и игра следует его развитию, то игра никогда из статуса БЭТЫ не выйдет, т.к. двигло может развиваться всю жизнь

по факту получаем, что альфа-тестирование они проводят не качественно, может человеческий фактор?
бета-тестирование - отсутствует !?!
в итоге релиз, который исправляется набором патчей и улучшений

по моему мнению, NEC хорошо получился, по сравнению с косяками первых 3-х маршрутов, ошибок много, но они не так глобальны, исправят в итоге патчами
с другой стороны, они компенсируют наш подломленный моральный дух предзаказами и скидками

Да, цена для России весьма гуманная, особенно с учётом скидок. В Европе и США это всё дело намного дороже стоит.

Купил себе игру во время новогодних скидок, взял ещё и пару DLC. Cказать чтоб я очень доволен?? Нет и ещё раз нет. Игру пока и близко нельзя назвать релизной. Ценик у DLC просто конский, а качеством они особо не славятся, пока что я вижу как все болячки Railworks перетекают сюда. Последнее DLC что релизнулось я вернул через 20 минут оно вообще ни о чём, скучное унылое и багованное. До кучи по расстоянию оно и урезано, в Railworks оно было длинней. Если всё продолжится в таком темпе то буду завязывать с этой игру, не вижу смысла поддерживать этих криворуких разрабов. Я ждал хороший жд симулятор а не сборище багов да ещё и с плохой оптимизацией.
