Button Outline Hover Color : Sets button outline color when mouse is over button. Better point size algorithm : The scalable algorithm has also been improved and a fixed point mode has been added. This new mode can be especially useful when working with a noisy asset. Improved Performance and Stability : Several improvements to the processing and streaming of the point cloud data have significantly improved performance for the end user.

Simple Gap Filling : Points are enlarged and rendered using a new technique that minimizes visible overlap. Disable Frustum Culling : It is now possible to disable Frustum Culling which can help with the data stream delay when shooting cinematics. With Unreal Engine 4. Pixel streaming provides new options for deployment, making it possible to stream Unreal's first-class realtime rendering to a wider array of devices and users than ever before.

While the workflow for setting up pixel streaming applications is fundamentally the same, this release comes with several key improvements and new configuration options. You can now deploy pixel streaming applications with Linux server instances, which provide many advantages in efficiency, scalability, and overall ease of deployment.

This improves the latency and quality of streams, and prevents them from degrading over time, and improves compatibility with most web browsers, including Firefox and Safari.

The improved WebRTC also provides support for audio input from users' browsers, making it possible to capture microphone input in pixel streaming applications. What's more, captured audio can be spatialized or processed once it is in the engine. The GPU Lightmass system continues to improve its progressive lighting baking with support for more features of Unreal Engine 4.

Support for more light parameters such as attenuation, non-inverse-square falloff, and rect light barn doors. Irradiance Cache is now enabled by default and is significantly faster for real-world scenes, and solves issues present in UE 4. The new default halves the speed to 8 instead of For more information, see the GPU Lightmass documentation.

The Path Tracer is a progressive rendering mode in Unreal Engine that can render the scene without any additional setup needed. The Path Tracer closes the feature gap of the real-time Ray Tracing features with physically correct and compromise-free global illumination, physically correct refractions, feature-complete materials within reflections and refractions, and super-sampled anti-aliasing.

For 4. Support for most light parameters, such as area size, penumbra, attenuation, Rect Light barn doors, Rect Light textures, IES profiles, and more. For more information, see the Path Tracer documentation. The Hair and Fur rendering and simulation features of Unreal Engine. Many of the improvements for visuals and performance have been driven by the MetaHuman Creator , starting with Unreal Engine 4. The ability to import a groom that has already been simulated and contains cached per-frame hair data.

During import of an alembic groom, the importer detects if the groom has animation. If so, it automatically generates two Groom Caches, one for the strands that have been animated and one for the guides that have been animated, which uses simulation to animated the strands being rendered. Ray tracing features continue to expand coverage and improve workflows for existing supported features. This release includes the following improvements and additions:.

Niagara particles in reflections now support particle-driven material attributes, such as BaseColor. Previously, particles seen in reflections were missing all per-particle features in their materials. Refraction is now controlled from the Refraction input on the main material node rather than derived from the Specular input. This now matches traditional raster methods for controlling refraction in transparent materials. Re-enabled Transparent objects shadow casting which was disabled in Unreal Engine 4.

Real time ray traced shadows of transparent objects can only be opaque. Partially translucent ray traced shadows remain limited to baked static lights. Shadow casting for transparent objects can be disabled:. For more information, see Real Time Ray Tracing documentation. Oodle Data compression provides the fastest and highest ratio compressors for game data. This product family provides four compression algorithms to best fit your project's needs.

Oodle Data decompression is significantly faster than other codecs and the algorithms run on all Unreal Engine-supported platforms. Oodle Data Compression is now enabled by default in Unreal Engine, providing significant compression and faster loading for packaged projects. Oodle Texture compression are the fastest and highest-quality encoders for block-compressed BC1-BC7 textures. Oodle Network compression is a unique solution for real-time compression of network traffic, greatly reducing the bandwidth required by game servers.

This solution works on all TCP and UDP network packets and significantly reduces the minimum bandwidth required for multiplayer games. Oodle Network compression is used by Fortnite already, and can be turned on and trained for your game's own network streams. Bink Video is the most popular video codec for video games and now it's built into Unreal Engine. It is a performance-designed video codec - decoding up to 10 times faster than other codecs, and using 8 to 16 times less memory. On some platforms, Bink decoding can also be offloaded onto GPU compute shaders for even faster performance.

Bink Video is completely self-contained nothing else to install and has an easy-to-use Unreal Engine plugin interface. The platform-specific plugins are still available in 4.

By default, the engine will prioritize the plugins based on device compatibility, in the following order:. The template is designed to be a starting point for all your VR projects. It includes encapsulated logic for:. See VR Template for more details. With fixed foveated rendering, you can use image-based variable rate shading in VR headsets to adjust the shading rate for a target. Fixed foveated rendering delivers a performance boost with little perceptual degradation in image quality.

There are four levels of fixed foveation provided: disabled, low, medium, and high. Starting with 4. Containers provide an option for packaging applications and their dependencies into a single, portable unit that can be deployed either on a local machine or through the cloud. This works similarly to virtual machines, but containers are more computationally lightweight, facilitating a larger number of concurrent deployments.

Based on the open-source infrastructure developed by TensorWorks and the Unreal Containers community initiative, Unreal Engine supports two types of container images: development images, which contain Unreal Editor and its build tools, and runtime images, which can run packaged Unreal Engine projects.

This makes it possible to widely deploy your development tools or your end-user applications to the cloud. For more information about the many ways you can take advantage of containers and container images, refer to our Containers documentation. Enhanced Input is a streamlined but highly configurable input handling system supporting runtime input remapping and complex, customizable trigger rules.

The experimental Data Registries plugin helps developers create efficient, global storage spaces for struct-based data tables. With Data Registries, you can access data synchronously or asynchronously, load data on demand, set up caching rules, and even extend the system to write your own indirection rules. Unreal Engine as a Library makes it possible to build the UE4 runtime as a library and interact with it through a minimal, built-in API with the following capabilities:. Runs UE4, optionally accepting a command-line and a client window where the engine should send its output.

You can also expand the API to suit your needs, exposing existing or new functionality for external use. The Georeferencing plugin associates physical locations, like an area of a planet's surface, with virtual locations, like UE4 levels.

You can convert coordinates between four coordinates systems:. Because the system is not limited to real-world, or even realistic, locations, you can use it to describe locations in any large world, round or flat, with consistent spatial relationships. Implementations are available on desktop, console, and mobile platforms, and support cross-platform online functionality for games that want to use these features.

Some of the available functionality includes:. Authentication flows both with and without Epic Account Services EAS as well as authentication through third party providers. Functionality for the Epic friends list, including social interactions supported by the overlay UI along with player info and presence updates.

Dedicated servers and player hosted matches, along with built-in support for peer-to-peer connections. The implementation is available on desktop, console, and mobile platforms, enabling cross-platform voice communication. With the new Online Subsystem EOS plugin, you can activate voice chat for lobbies, which will enable participants to automatically join the corresponding voice channel. The system automatically creates an IVoiceChatUser interface that you can access through Online Subsystem EOS for further interaction and updates with the lobby voice channel.

Quartz can now run without an audio device. This new feature provides the ability to run Quartz on a dedicated server. Quartz has new Clock Handle Blueprint functions that provide audio designers with quality of life improvements - including starting, stopping and pausing the current clock. Quartz can also start another clock on a sample accurate boundary, so audio designers can switch between the two clocks at runtime. This can be used to facilitate time signature changes by seamlessly switching to another clock.

This can be used in conjunction with the new "Reset Transport Quantized'' Blueprint function to hard-reset the clock to stay in sync with external devices. You can use these by enabling Mobile HDR and following the same steps to use these anti-aliasing post-processes on a desktop device. The Mobile Deferred Renderer's performance and stability are significantly improved, and it runs on a wider range of Android devices. Android projects can now use the Visual Studio debugging workflow.

You can then use it to deploy and debug projects directly from Visual Studio. This makes it possible to use the Android memory profiler for Development, Test, and Debug configurations without the need for workarounds. For more information about how to use the memory profiler in Android Studio, refer to Android's documentation on the Native Memory Profiler. This fixes issues with native string visualization in Android Studio, and makes Unreal data types available without needing to perform any extra setup in your Android Studio projects.

The Command Line Encoder can be used to create your own output format from 3rd party software, such as FFmpeg. You can now group your objects based on actor name, material, folder, and more.

To improve ease of event track navigation, we have added a shortcut to opening the Event Track's Director Blueprint in the sequencer toolbar. In addition to the Start Record button in the Take Recorder tool, we have now also added the button to Sequencer's playback controls. Sequencer's record button allows recording of any selected Actor into the current sequence, and does not require the Take Recorder window to be open.

When the Movie Render Queue plugin is enabled, you will now have the option to choose which renderer you want to open when clicking Sequencer's Render button. You can either specify Movie Render Queue or the legacy renderer. Template Sequences now support multiplying properties.

Property multipliers will allow your template sequence instances to have varied intensities, while still referencing the original asset. A new track has been added to Sequencer to allow for triggering notify states on Actors built using the Gameplay Ability System.

Like notifies, the Gameplay Cue Track can utilize range-based events or trigger-based events. Various options exist on the cue to customize how it is triggered, including controls for the instigator, location, or attachment. You can now version a module, function, or dynamic input. This gives you flexibility when making your own modules, since you can set the functionality and then save it to a version number. When you create new versions of a module, those new versions become available to users.

The first time you add the module to your Niagara system, it will use the version designated as exposed. As new versions are added to that module, you will have the option to upgrade to new versions or revert back to previous versions. This feature also includes python integration to automatically transfer existing inputs to any new module version on upgrade. For more information, read the page Module Versioning in Niagara. Starting in Niagara 4. These examples are designed as very simple Niagara emitters that show one aspect of Niagara.

This can help new learners to understand the technology. A new panel has been added to the Level Editor called the Niagara Debugger. This panel gives you the ability to understand and debug Niagara simulations in your level and see what is happening at runtime.

You can toggle the Debug HUD on the viewport to display information about the Niagara simulations in your level. You can pause the simulation, or play it at slow speed to see what is happening over time. When you activate slow motion in the Niagara debugger it only slows down the Niagara particle simulations in the level, the rest of the level plays at regular speed.

You can also turn on a data readout of each individual particle. There is a new Debug Drawing option on some modules such as Sphere, Box, and more. When enabled, it will show a visual representation of the module. You can then debug your system and adjust the parameters of the module as needed. If Debug Drawing is available on the module, a blue box will appear to the left of the checkbox on that module. To enable Debug Drawing, click on the box. If you have Debug Drawing enabled on more than one module, you will see a drawing for each shape.

Debug Drawing can also be used to track the path of individual particles. The below example shows what it looks like on a fluid simulation. You can now add more than one mesh to a Mesh Renderer. By adding more than one mesh, you are creating a Mesh Array. You can either randomly spawn particles of those meshes, or you can use them in a sequence as a flipbook.

To add more than one mesh, select the Mesh Renderer. Click on the plus sign to add an additional mesh to your renderer. You will notice that each mesh is assigned an integer value starting with 0. To create particles randomly using meshes in the array, click on Initialize Particle. You will now find the attribute particles. For example, if you want to have the particles change randomly over time then you can drag particles.

You can then set the MeshIndex parameter to Random Range Integer and have it cycle through as many integers as you have meshes set in your renderer. In the Mesh Renderer there is a section for you to set the array as a flipbook if you have a series of meshes that should cycle over time. The Curve Editor within Niagara has been updated to match the curve editor used in Sequencer.

This gives you more advanced editing tools to adjust keys and retiming. The Curves panel has been redesigned to show a hierarchy of all the curves in the system. You can search through the hierarchy and pin curves that you want to have quickly accessible.

Double-clicking on a row in the curve overview will open up that module in the Selection panel. Inline curve editors, which are displayed in the Selection panel, have also been updated. Click on curve Templates to quickly apply commonly-used curve shapes. You can also navigate quickly through keys using the arrow buttons at the bottom of the Curve editor. You can also create your own curve templates in the Project Settings if you have a commonly-used curve that is not already a preset.

There have also been performance improvements on the Curve Editor in this version, resolving an issue that was causing slowdown when dragging keys. There is a new asset in Niagara called Parameter Definitions. You can create a Parameter Definition to define default values and descriptions for any number of System, Emitter, or Particles namespaced parameters. These default values and descriptions can be referenced in Niagara Emitters, Systems, and Scripts.

Any reference to a Parameter Definition in another Niagara asset is automatically subscribed, or linked, to any changes made to the parameter in the Parameter Definitions asset. For example, you could use this to automatically push changes to a parameter's name, default value, and description out to all references of that parameter.

In previous versions, the Ribbon Renderer would always output a flat plane for the ribbon. Now, you can choose between a plane, multiple planes, a tube, or input vertices for your own custom shapes. To enable these options, see the new section in the Ribbon Renderer called Ribbon Shape. Depending on the type of shape you have selected, different options become available to adjust the shape.

Keep in mind when trying these options that you may want to set the Facing Mode in the Ribbon Renderer to Custom instead of Screen. Along with these additional options, you can also set new parameters to help reduce artifacts in ribbons. When Ribbon Shape is set to Plane or Multi Plane , you can adjust the Width Segmentation Count to add additional vertices to the mesh so that it deforms more smoothly. When Ribbon Shape is set to Tube , you can adjust the Tube Subdivisions to add more vertices to the tube.

You can use the Niagara Script Stats panel to compile your Niagara system for different platforms within the Niagara editor. This will give you information on any platform-specific errors without the need to cook. There is a new node for Niagara scripts called the Select node.

This replaces the now-deprecated IF node. You can specify a selector type integer, bool, or enum. You can also select various values at once.

Depending on the value that is input into the Select node, it will output a value. The above example shows a Select node set to boolean. It will check to see whether a given input is true or false. You can also create a Select node from a list of Enums. In this following example, the Select node is created from Scale Sprite Size.

It is then populated with all of the options that Scale Sprite Size could be set to. There are two new nodes for hash functions, Hash Integer and Hash Float. By providing a set of integer inputs, they will output a random value. The difference between the Hash functions and the Seeded Random is that given the same inputs, Hash will always output the same value even across function calls.

In contrast, Seeded Random will generate a consistent value per function call. There have been a number of user experience improvements across the Niagara editor. This is included but not limited to:. Hotkey support for Niagara: J and K to cycle forwards and backwards in playback. S to isolate selected emitters. D to disable selected emitters. Suggested feature that lets you pre-label an asset as Suggested. These actions will appear at the top of the list as a section during search. In the case of dynamic inputs and modules they show at the top without searching.

In every release, we update the Engine to support the latest SDK releases from platform partners. Visual Studio - Visual Studio v The Environment Query Editor is now an engine plugin that is enabled by default; Individual users are no longer required to enable it through the experimental settings.

The editor is still considered experimental and disabling the plugin will remove access to the feature. Made the UE4ML plugin public. Switched AIPerceptionSystem's stimuli aging from previously using a timer to now counting elapsed time.

In normal circumstances this doesn't make any difference, however, this change does help when trying to use the perception system in replays where UAIPerceptionSystem::StartPlay ends up not being called. Added a blueprint-callable function to AIPerceptionComponent.

Bit fields located in the PawnAction class have been optimized to pack into a single 32 bit allocation. Added a tiny optimization to avoid calling AIPerceptionSystem. OnNewPawn when the perception system is configured to not care about new pawns. Dynamic EnvQuery graph node titles will now update correctly when properties in their details panel are changed. Fixed issues in AIPerceptionComponent where perceptual data associated with actors were no longer valid and being broadcasted through delegates.

Added validation on instance arrays aux nodes, parallel tasks and memory to update stats properly and to prevent modifications while iterating through them. Fixed an issue where iterating through active nodes would sometimes cause a node to be deactivated. Fixed an issue where the BT evaluation of a Conditional Flow Abort skips a higher priority state if the evaluation triggers another Conditional Flow Abort in the previous state.

Fixed an issue where a BT task was being executed even though it had lower priority than another task higher in the hierarchy. Fixed a computation issue of a child execution index of a composite node when the child is a task node with services.

Added the ability to select the local player for debugging in GDT through the command "gdt. When using the right mouse button the Timeline will no longer snap to the closest element as it interferes with panning. Fixed an issue where clearing debug data would not properly clear the stored EQS debug drawing text.

Added the Console variables ai. Fixed the convex element export in the NavModifierComponent to improve the precision of navmesh generation around those elements. Fixed an issue where the Navigation Mesh was making the current map "dirty" on load without any user action. Fixed an issue where unloaded levels were being added to the NavOctree, impacting the Navigation Mesh. Prevented the Navigation Mesh from being removed when a level is saved without a Navigation System.

It is now possible to import an animated groom through Alembic as a GroomCache asset and play it back on its associated Groom asset through the Groom Component. Fixed a potential crash with Level of Detail Material mapping which occurred during a Skeletal Mesh merge. The Animation Blueprint Transition warning when the rule is bound is fixed. Pins are automatically disconnected if they are replaced with a bound rule.

RandomPlayer anim node will now support blend in times that are less than the frame delta, including 0. Re-ordered AnimInstance's property access class method to copy after Event Graph methods in order for properties to be correctly transformed when accessed from Blueprint functions.

ControlRig AnimNode's exposed pins will now have the correct default values as specified in the source Control Rig Blueprint. Fixed Animation Blueprint compiler issues occurring with collapsed graphs and isolated errors in state transitions. Fixed debug drawing of raw animation bones in Persona when component has post process or sub anim instances. Improved support for GeometryCache starting with empty frames, such as fluid simulation, explosion, and other effects.

Fixed crash that would occur when importing a SkeletalMesh from Alembic with the "Merge Meshes" option. This results in cleaner subframes. Updated Quartz with the ability to query for the duration of time that a given number of Quantization Type events will run based on the clock's sample rate and time signature settings.

Added a new log category for stream caching to independently control log levels from the logaudio category. These booleans replace the previous "Output to Bus Only" parameter. Assets created prior to 4. Reduced memory overhead when using SoundCues by pruning branches that do not match the cooking target's quality level.

Fixed an issue where using a Submix Effects chain in Blueprints would cause a crash if no Submix Effects Preset was found. Fixed issue where Sound Classes would sometimes load before certain referenced types could be known, breaking those referenced assets. Fixed issue where sometimes a "divide by zero" check would get triggered if Quartz was using very high BPM.

Fixed issue with Vorbis in which it failed to load streamed data before the initialization phase was over. This primarily impacted Multichannel streams where the initial pages couldn't fit into 6 KB. Fixed an issue where the multi-channel source bus was using the number of frames instead of the number of samples.

Fixed an issue where restarting in virtual mode would not properly reset the active sound cue and playback time.

Fixed an issue where the multi-channel TSampleBuffer was using the number of samples instead of the number of frames. Fixed the Replace All Reports feature in the Test Automation window not functioning the first time it is used. Prevented watched pins from causing ControlRig Editor to keep marking a ControlRigBlueprint as dirty after being saved. Commandline argument "-buildmachine" now propagates to subprocesses like ShaderCompileWorker started by the engine.

In the editor preferences the "Enable Live Coding" option no longer requires an editor restart to take effect. Added messaging about delays to live coding to accommodate cases where the Unreal Editor has stopped in the debugger when a system using a large number of processors. Improved live coding feedback in the Unreal Editor when compiling is initiated using the keys Ctrl-Alt-F Added a UTickableWorldSubsystem as a base class for all world sub systems that need to be ticked along with their world.

By default:. Editor asset tagged property loading is now more resilient by seeking the expected end position and logging an error, as opposed to setting the archive into an error state. Added support for UE as a Library, which enables external applications to run and control their own UE4 instance.

A new package option to specify the URL to where crash reports will be sent, in cases where the crash report client is packaged with the game. This option can be found in the advanced package options, by default crash reports from the Editor are sent to Epic unless otherwise specified.

Included the name of the slowest unit test in a warning log for when a less than two second smoke test run time is executed. Enabled comparison of string views of different types Compare, Equals, and the associated operators are now supported for any pairs of string views and C-style strings that FPlatformString has a comparison function for.

Added RetainedRef Template to be used as a function parameter when the reference will be held beyond the length of the call, causing a compile error when passing an rvalue. Smoke test responsible for finding uninitialized struct members will now also try to construct all structs with 'new FMyStruct' syntax to find properties that are uninitialized despite their struct having a custom default constructor. CSV file with events stripped.

This skips CSV processing entirely for files already in the cache, which is significantly faster for bulk queries. This makes the summary table scrollable, with frozen first rows, columns, and automatic colorization. These are useful for historical data tracking. Added Csv. Run CsvConvert with pass -binCompress 1 or 2 to enable compression on. Updated clang atomics to use newer atomic functions in favor of sync and added support for bit atomics for platforms that support it.

Added Support for multiple wildcards in arbitrary positions has been added to CsvTools. Added a checkpoint heartbeat hang detector to help diagnose issues such as infinite loading screens. If it takes longer than the threshold to reach MonitorCheckpointEnd, a fatal error will be thrown.

Added MakeBinaryConfig commandlet. This will optionally run at stage time to generate a BinaryConfig. FObjectIterator has now the option to lock the global UObject array when it's iterating over it to prevent thread safety issues when iterating over all objects while other threads are creating new UObjects.

Optimized the time required to resolve call stack symbol names on Windows OS. The Engine now loads and caches the debug symbols on demand rather than loading all debug symbols at once on the first request. Saved one-hundred and twenty milliseconds to next gen load time by removing superfluous sleeping on a critical path.

Fixed crash when polling to see if a UTexture is ready for PostLoad while it is processing it's texture data on a background thread. Fixed a crash that occurred when working with map instanced properties if the map's sparse storage has gaps.

Garbage Collection will now treat cluster objects with Internal Object Flags set to Garbage Collection Keep, the same way as if they are in the root set to prevent them from being destroyed while being referenced by the async loader. Fixed hot reloading where a change would not be detected due to a mismatch between how Unreal Editor and Unreal Build Tool formatted the module name.

Fixed an error where changing projects from the Unreal Editor which had been "Quick Restarted" from the live coding console would result in the Unreal Editor failing to start properly. Fixed issue where live coding fails to compile changes when both the editor and game are running. Added a missing call to the EngineSubsystemCollection Deinitialize method when on engine shutdown is invoked. GC weak references will now be cleared after gathering unreachable objects as more objects become unreachable during the process.

Fixed FString class method SanitizeFloat from returning "0. GarbageCollection: Changed InternalObjectFlag priority to make sure that objects are not being destroyed while being referenced by the async loader. Fixed a problem in ArrayProperty's SerializeItem method when using a user-defined structured archive formatter, caused by a mismatch between the saving and loading branches when doing unversioned property serialization.

FMallocBinned3 will now try to allocate memory from a bigger pool to avoid Out of Memory crashes. Due to Windows 7 no longer being supported by Microsoft, the bundled version of DbgHelp. Prevented an object from being accessed from weak pointers after it's been destroyed and fixed a race condition between FWeakObjectPtr and Garbage Collection AsyncPurge. Changed the checkSlows to checks in theFixedAllocator template to allow them to detect user error in Development builds.

Added static assert to detect inherited Structs which are not polymorphic unless inherited base struct also is polymorphic. If this happens, there are two options:. OutputDeviceRedirector's buffered lines will now only be emptied if there are any output devices to redirect to.

Fixed a potential concurrency issue when renaming objects and enabling UObject hashing error asserts in development builds. Async loads from the async loading thread during the final async loading flush will now also be allowed to prevent a safeguard from firing. Async loading will no longer be allowed after the final async loading flush to prevent crashes on exit.

FPackageReader will now copy the Editor only filtering flag from the underlying reader archive to the owning package reader. AssetRegistry EditorOnly dependencies. Added a cooker parameter which allows DLC cooks to override the platform name used to find and load the development asset registry. Allows different platforms to use a single registry where that makes sense. Re-added a "Check All Connections" checkbox functionality in network profiler that got removed by mistake.

Fixed issues with network profiler graph view not loading if there are fewer than 30 frames worth of data in the profile. Actor visibility attribute is now serialized.

An exporter can decide to export hidden actors that way. A Datasmith scene can now declare new materials that inherit existing Material Instances and override their parameters.

Datasmith Revit exporter provides Floors and Ceilings pivots at scene origin instead of at their own local pivots. A processing time control in CADWorker has been added. This prevents a DMU from not being imported due to a referenced file looping. The processing max time is based on the size of the file to process, and its format.

Only the blocked file is canceled. This can be disabled with cvar r. Update of KernelIO dll with sp1.

With this new release, the supported version by format are:. Added new Collaborative Viewer content: two new templates in Collab Base that use shared resources. For the Navisworks importer, Mesh Actors for merged geometry are now re-pivoted to the bottom center of the bounding box. A crash no longer occurs when an asset referenced by a captured UObject property in the Variant Manager is swapped with an asset of an incompatible class.

Fixed a crash that occurred when trying to capture Variant Manager thumbnails from the viewport during standalone mode. Fixed the Variant Manager spawning function director outer ALevel Variant Sets Actors so they always spawn on the persistent world levels instead of on the vestigial worlds of sublevels.

Fixed the Variant Manager function directors that were unnecessarily collected and recreated repeatedly. User-set Material overrides are no longer replaced when reimporting Datasmith scenes in some scenarios. Fixed an issue where Variant Manager visibility changes were not applied to the viewport on some scenarios when the viewport's Realtime property was set to Off.

FDatasmithSceneCleaner::Clean will no longer remove materials that are referenced only by a variant. Fixed incorrect exported joint indices when exporting skeletal meshes to USD if the skeleton has a different number of bones than what is used by the skeletal mesh. Fixed an issue in the material generation by a datasmith import. The expression names in the material functions used by a Datasmith-created material are now unique. Tweaked triplanar projection, added panning in triplanar, tweaked glass default values, and added decals material permutations.

Fixed a broken documentation link on the import help button and added an automated test to make sure the link stays valid. Added a custom solution section to allow Visual Assist to identify the solution as an Unreal solution.

The full path to the VsCode compiler is now specified, as well as command line arguments in the format expected by the compiler. Corrected an issue with degenerate artifact creation. Attempting to create files with the same source and destination folder hierarchies when the Role was null would lead to file errors.

These required five second timeouts each to skip when ending runs using -skipserver. This led to problems in the CI pipelines, the CI stage was sometimes assumed to have failed despite the fact the tests were ok and the tests' status code was 0. This now reduces the time it takes to Launch the game from the Editor.

Fixed staging chunk assignment failing when there were case mismatches between paths in the staging manifest and the pak chunk lists. Corrected a case during project param creation where we still assumed there was a single editor target per project. Fixed issues when running UBT in a build environment without a local data directory, by falling back on the Engine folder.

The ExpandEnumAsExecs metadata now properly handles spaces in a comma-delimited list of parameters. When toggling sub-level visibility on the Levels Editor, Multi-User editing now reflects the corresponding game flags so that -game nodes will properly display updated visibility.

Users can opt-out of this behavior by disabling the Reflect Level Visibility to Game option in the Multi-User project settings. The spline point property editor now allows toggling between absolute and relative position and rotation. Added Copy and Paste options to the context menu on each field of the spline point property editor. Package save events are now captured when running in -game mode.

This is to support remote recording of takes on headless nodes. API users can indicate if a UProperty or UObject should be included, excluded, or have default behavior applied to it.

Added support to nDisplay to properly synchronize Multi-User activity stream when the nDisplay nodes first connect to the session. All nodes will coordinate their activity sync and they will finalize simultaneously. Note: If a node reconnects during an active session after initial synchronization, it is no longer possible to synchronize it. All nDisplay nodes should be restarted if synchronization is required. Multi-User take recording is now automatically available when connected to a Multi-User session.

Previous versions required you to enable a special CVar. Added a new Editor preference Check References on Delete. When disabled, Unreal Engine no longer checks actor references when deleting actors from the World Outliner or warns about possible lost references. This can reduce the delay of initial deletion for levels that contain a lot of soft references.

Users can now control the maximum transmission rate for packets on a UDP connection. Users can now use new controls in the Take recorder to specify who is recording and who provides the source data to nodes connected in a Multi-User session. This feature is only enabled when connected to a Multi-User session.

Reference Viewer now has a Compact Mode that hides thumbnails on the graph nodes and reduces the space taken by each one. It allows the insertion of secondary assets that should be deleted at the same time as the ones selected by the user.

Added an option to UTextureFactory to specify the source image color space. This saves processing time when importing MDL materials by creating the textures with the right color space at the factory level. You can now load a material from a module path and a definition name instead of loading it from a file.

You can use IPv4 style addresses or a named address. Added support for changing the aspect ratio axis constraint when the viewport is locked to an Actor. This reduces the number of source control operations needed when working with large numbers of files. If you're already using the global DDC environment variables, these will remain in use. Added per-project settings you can configure to recommend the setup of a globally shared DDC. These settings are off by default.

Added default color and grayscale calibration chart materials to Engine content and BaseEngine. Added the -FrameproEnableContextSwitches command-line interface argument to turn on context-switch tracking in Framepro captures. For the MDL Importer, imported material graphs no longer contain unused constants and parameters.

Removed a message dialogue from skeleton processing to fix a crash with destroying SAssetPicker while it is rendering thumbnails in its Tick. Fixed a crash that occurred when trying to use Blueprints derived from AUsdStageActor in standalone mode. Fixed an issue where water actor sprites would not load due to Water Subsystem being nullptr in the actor constructors.

Fixed a bug where the first texture imported in an Editor session could have the wrong settings applied to it. ConfigureEnabledPlugins now reports success when plugin count is zero.

Contributed by WenchaoXia. Fixed an issue with a sub-level not being garbage collected properly when creating a new world from a template. Fixed a sub-level offset issue that happened when loading a top-level world in World Composition when that sub-level had been already loaded. Added a missing water sprite category in the viewport options. Billboard components now need to be added to the CDO in order to be detected by the Editor as proper sprite categories.

Fixed an issue that caused the icon for river water body actors to appear oversized the first time a water actor was placed in the level.

Fixed two separate issues that prevented the Goto Definition Editor feature from working in relocated Installed Builds. Added support for displaying floats greater than e18 in the Editor, and removed cast losing double precision. Fixed a bug that prevented reporting when not using the crash reporter. Contributed by Phyronnaz. These additional deferred actions are then immediately processed in the same frame. Fixed a bug with instanced objects not updating the reset to default state in the parent object when changed.

The Paint tool is now correctly grayed out when painting textures with mesh paint if the mesh has no paintable textures to cycle through. Fixed an issue that caused a missing portable call stack in the crash report generated when the Editor had more than threads and the crashing thread was not in the first threads visited by the OS. Fixed an issue that caused sublevel components to fail to toggle when changing sublevel visibility in the Editor.

Fixed an issue that caused the crash reporter UI to sometimes take several minutes to process and display crash information after an Editor crash. Fixed an issue where specifying multiple TCP connection endpoints from the command line did not work. Range selection in the Persona tree view now behaves correctly when the initial selection is made from the viewport and the second selection is made from the tree view.

Fixed a bug that caused disabled toolbar combo buttons to incorrectly appear enabled when shown in a sub-menu. Fixed an issue where some Asset editors would end up in a non-functional state after a window closing request was canceled, including the Blueprint Editor showing 'Unrecognized Tab' panels.

Preview widgets are now marked as being in Design mode before being destroyed, to prevent them from invoking NativeDestruct in the Editor. Added ConditionalPostLoad call before building collision on a display mesh, fixing a potential issue where complex collision meshes didn't work properly in PIE.

Fixed an issue with FBX exporting where multiple meshes with the same material would receive the default material instead. Fixed a vulnerability due to an integer overflow and a heap overflow when loading a modified TGA file. Fixed 'More Actions' menu items not doing anything when using the embedded gameplay tags editor within the Blueprint editor details panel.

Fixed an issue where transform changes were applied twice to attached Actors when selecting both the Actor and its parent. Fixed an issue where expansion state was not being properly retained in trees with more than items. Fix a crash that happened when syncing out of date Assets in the Editor if a dependency package was not found. Fixed a crash that happened when importing an OBJ file and using the create instanced materials option. Fix an issue that caused a duplicate copy of a package to remain on disk with the old name when renaming the package.

Base brush properties size, strength, and falloff are now correctly restored after leaving and re-entering Mesh Paint mode. Fixed an import problem with FBXs containing LODs with meshes which could not be triangulated for example, due to being non-manifold. Problematic meshes will be omitted and a warning will be generated. If a LOD cannot be imported at all, it will be auto-generated instead.

Reimporting a. FBX file no longer deletes custom metadata on the reimported assets. Only the FBX metadata are now affected by the reimport. Fixed an issue where the FBX import would wrongly assume the importing of a skeletal mesh when the FBX file contained animation but no skeletal mesh.

When importing a FBX file, fixed an issue where some custom curves configurations were not properly imported, causing incorrect tangents. Fixed a bug in the editor which would open the file selection window twice when reimporting an asset with the "reimport with new file" option.

In MDLimporter, clears the log error when an. UParticleModule is now marked as within ParticleSystem to prevent instancing with other outers, which caused several crashes. Fixed a bug that prevented any type of Haptic Feedback assets from being created in the Content Browser. Fixed a bug that caused thumbnails for child Blueprints which override parent Blueprint data to render incorrectly.

Fixed an issue where files could not be dragged into new folders in the Content Browser's column view. Optimized source control operations when renaming Assets to fix a large stall when renaming or moving a large number of files. Prevent crashes when creating mesh sections in ProceduralMeshComponent with out-of-bounds vertex indices or non-unique vertex indices within a triangle. When a material function changes, all in-memory material functions are now checked to see if they use that function, and recompiled if they do.

Vector parameter children should now be editable as expected when the vector parameter is overridden. Merged alpha manipulation function into one shader. Media capture options allow you to force the alpha channel to be set to 1. This is useful if the render target doesn't have an alpha channel. Fixed a crash that happened when the Preview Scene Settings tab was spawned before the Viewport tab.

This attribute will change how the light surface is calculated when converting USD light units to physical light units. If a sphere light has the schema, a spot light component will be generated in UE and its cone angle will be set according to the cone angle attribute. Added support for USD render contexts. When parsing materials, Unreal Engine will now load the shaders associated with the requested render context. Added support for the UsdLuxLight exposure attribute when calculating the light intensity for Unreal.

Attributes will now be written out to the default time code instead of at the UsdStageActor time. Added an asset cache to speed up reloads for USD Stage actors. Textures can be persisted in the cache and won't be recreated unless the source file has changed since the last time it was processed. Detailed instructions can be found within the script itself. More warnings and feedback have been added for when the prim configuration is incorrect for the parsing of LOD meshes from USD files.

Most operations and attribute changes are now tracked. There has been a complete rewrite of the level exporter to USD to add support for exporting foliage, landscapes and sublevels, and to update legacy scripts to Python 3.

Back light and camera component property changes are now written to the opened USD Stage when edited on spawned components. This now shows along with more data when no prim is selected; additionally, the stage now shows as the root prim entry on the stage tree view. Changed how the Usd Stage Actor binds stage loading and unloading to actor lifecycle functions. This provides more predictable behavior in complex scenarios like level streaming, switching levels during PIE, and Movie Render Queue operations.

Changed the USD material import workflow to use master materials instead of generating new materials on each import. No longer crashes during reimport of a material from USD when the original replaced material is currently in use on the scene. Fixed an issue where the cubemap was not getting assigned to the SkyLightComponent if the texture was already cached.

An issue where USD AnimSequence exporter was not, in some cases, finding a preview mesh to export with has been resolved. The stage now properly closes and reopens when the USD Stage Actor is in a streamed sublevel that is hidden or shown. A warning now displays if cubemap is not found on the filesystem when setting it onto a USD prim. Incorrect color space conversion was corrected when importing vertex colors from USD geom meshes.

Fixed an issue so skeletal meshes are no longer visible on the viewport in some scenarios after exporting UAnimSequence assets as USDs. Fix camera transform orientation compensation when writing back camera transforms to the USD stage. Spawned components are no longer left in an invalid state after undoing a transaction where their owning AUsd Stage Actor is deleted.

This fix included a way to add USD layers as a sublayers of themselves. Disabled the placement of VR editor mode gizmo actors from the place actors panel.

This prevents the VR gizmo actors from saving into a level and causing a crash when that level is deserialized. Fixed an issue where the Level Browser would lose folder information when switching streaming type. Action level modifiers and triggers are evaluated in a second pass, after all mapping level modifiers and triggers. Added new Blueprint Compiler options and internal reinstancer flags to allow users to enable delta serialization.

Camera modifiers; including Camera Shakes, will now affect post-process settings. This makes it possible to add a Sequence shake pattern onto this class, because Matinee is deprecated and will be removed in a future version. Moved Camera Shake implementation in a "shake pattern" class, leaving the base class as a container. This is to make it easier for artists to change a shake completely without having to make a new one, as well as for programmers to write new shake behaviors that can work with existing ones.

When restarting a single-instance camera shake that was blending out, the current blending weight will transfer into a blend-in if appropriate.

Sequence camera shake can now animate post process settings, and better handles the difference between focal length and field of view.

Added API for scrubbing camera shakes. This results in better support for putting shakes inside sequences. Added more support to filter Gameplay Tags in the Editor using a project-specific filter. OnFilterGameplayTag supplies the referencing property and the tag source, so you can filter tags based on what asset is requesting the tag.

Improved Asset Manager to support virtual paths like AssetSearchRoots that can be replaced with dynamically set paths. SAI comes with a full set of transformation tools that can work on selections, including move, resize, rotate, and a free perspective transform.

Any series of transforms can be set up and then applied at once to a specific selection minimizing the softening of the image.

Some common features that exist in similar software, such as text layers, gradients, and shape tools, are not implemented, as SAI focuses on drawing and painting, while the final composition is often done using another application. SAI displays white and transparency in the same way, which may cause significant display differences when exporting to another program, such as Adobe Photoshop. There is also no printing functionality, but documents can be exported in a range of popular formats, such as.

PSD or. BMP files, in addition to the native. SAI format. Users may use another program for more complex editing, but when the image is brought back to SAI, its properties may be changed. SAI also includes linework layers, which can be used instead of manually drawing linework. The linework layer include different tools designed specifically for creating lineart, such as the Line, Curve, Edit, Pressure, and Weight tool.

Various settings and features can be accessed and edited by the user either from the built-in Options dialog, or using the provided misc. Existing brush presets can be edited, and the user has the choice of adding custom ones by placing bitmap files into the "elemap" folder. New canvas presets, as well as custom brush textures may be added by the user, in the form of grayscale bitmaps.
