6000.6.7f1 Release Notes

Improvements

• Asset Import: Improved the security of model import by updating the bundled Autodesk FBX SDK to 2020.3.11, addressing two buffer-overflow vulnerabilities in FBX file parsing. (UUM-155199)

• Graphics: Mesh-related memory should now be correctly labeled in the memory profiler (UUM-126926)

• Profiler: Improved native memory attribution so several kernel, plugin and file system allocations are reported against a named root instead of Unrooted in the Memory Profiler. (UUM-126921)

API Changes

• Editor: Added: Added HierarchyViewColumnDescriptor.MinWidth to set the minimum width of a custom Hierarchy column. (UUM-155402)

• UI Toolkit: Added: Added ScrollView.touchScrollDirection to make the content move opposite to the pointer when dragged with touch or a tracked device. (UUM-139596)

Changes

• Graphics: Changed AsyncGPUReadback to reject a readback whose destination NativeArray is still in use by a running job, and report the error through the callback instead of proceeding.

• Performance Test Framework: PerformanceTestRunInfo.json and PerformanceTestRunSettings.json are no longer generated during player builds that do not include test assemblies, as they are only read by performance tests running inside the player. Stale files left behind by an aborted test build are removed before such builds instead of being included in them.

• Physics 2D: "PhysicsComposer.AddLayer", "PhysicsComposer.ToPolygons", "CircleGeometry.ToPolygons" and "CapsuleGeometry.ToPolygons" now log the standard validation warning instead of throwing "ArgumentOutOfRangeException" when given no geometry, fewer than three vertices or an invalid "curveStride". (UUM-156367)

• UI Toolkit: Changed touch dragging of ScrollView content on world-space panels so the content follows the finger pixel for pixel, regardless of the Pixels Per Unit setting. (UUM-139596)

Fixes

• 2D: Fix duplicate global light error when building a player (UUM-153879)

• 2D: Fixed 2D lights changing position and orientation when rotating an Android device in projects built with Vulkan and Apply display rotation during rendering enabled. (UUM-147359)

• 2D: Fixed URP 2D editor-only icons being included in player builds. (UUM-144935)

• Android: Android: Fixed an issue where the Target API Level dropdown in the Player Settings saved an API level 6 lower than the selected one, which made builds use the wrong target SDK version. If you set the Target API Level in 6000.6.3f1 or a later version without this fix, select it again. (UUM-151786)

• Android: Fixed CanBuildWithSymlinkSources flakiness caused by parameterized runs sharing a temp export directory. (UUM-149303)

• Entities: Fixed an ArgumentNullException during Sub Scene import after clearing the Scene Asset of a Sub Scene.

• Entities: Fixed an issue where SubScene baking failed with an InvalidCastException when a baker used AddComponentObject to add a non-Component object, such as a GameObject, to an entity that also had a companion component. (UUM-99059)

• Entities: Fixed unsaved changes in a Sub Scene being lost when changing its Scene Asset and pressing Cancel in the save prompt.

• Entities: Fixed unsaved changes in a Sub Scene being lost without a save prompt when a duplicate Sub Scene that references the same scene was deleted or had its Scene Asset changed. (UUM-154590)

• GI: A Terrain added to a ray-tracing acceleration structure no longer leaks a Mesh and its GPU buffers. (UUM-151903)

• Graphics: Fixed an assert "Metal: memoryless texture requires 2D texture." that the Editor logged on Metal when it rendered single-pass XR to memoryless texture arrays. (UUM-154442)

• Graphics: Fixed an InvalidOperationException when a script disposed the destination NativeArray of an in-flight AsyncGPUReadback request on exiting Play Mode. (UUM-143136)

• Graphics: Fixed AsyncGPUReadback.RequestIntoNativeArray logging read/write access and undisposable errors for a NativeArray that was used by a completed job. (UUM-102552)

• Graphics: URP Decals shader could rarely produce NaN values on Android platforms when sampling non-normal-map textures set as the Normal Map, especially visible as white flashes when in conjunction with other amplifying effects like Bloom. (UUM-153167)

• Graphics: URP Decals shader could rarely produce NaN values on Android platforms when sampling non-normal-map textures set as the Normal Map, especially visible as white flashes when in conjunction with other amplifying effects like Bloom. (UUM-153167)

• IL2CPP: Fixed a crash when calling GetType() through a boxed Nullable<T> that has no value, in generic code built with Faster (smaller) builds. (UUM-152751)

• IL2CPP: Fixed issue where memory from a thread object could be kept alive by the GC past its exit (UUM-149541)

• Input System: This fixes Windows' Xbox Game Bar and macOS overlays (Spotlight et al). On Windows, Steam/Discord/NVIDIA overlays work as always. (UUM-150045)

• iOS: Fixed a crash when application:openURL or application:continueUserActivity was called before Unity initialized. (UUM-151801)

• iOS: Fixed the secondary display mirroring the device screen instead of showing its own camera view on iOS 27. (UUM-149106)

• Mono: Stopped a crash when using a default GCHandle (UUM-153835)

• Multiplayer: Restored the Multiplayer Center menu item for projects. First open attempt will installs the package and opens the Multiplayer Center window.

• Networking: Unity Transport: Fix a small memory leak that would occur when creating TLS/DTLS sessions. (UUM-151755)

• Package Manager: Fixed the Editor becoming unresponsive when the package trust window appeared during Editor initialization. (UUM-153544)

• Performance Test Framework: Repeat test-player builds no longer assign a fresh GUID to the PerformanceTestRunInfo.json/PerformanceTestRunSettings.json assets on every build. Previously, deleting these assets' .meta files as part of post-build cleanup caused Unity to assign a new GUID on the next build, which the data pipeline treated as a change and triggered a full asset rebuild even when nothing else changed. The .meta files are now cached in Library/ between builds and restored before the assets are rewritten, scoped to builds with test assemblies.

• Physics: Fixed Rigidbody.mass accepting a NaN value, which made the body pass through all colliders. (UUM-154143)

• Physics 2D: Added missing public argument validation for various Physics Core 2D methods. (UUM-156367)

• Physics 2D: Fixed a crash or memory corruption that could occur after setting "PhysicsChain.friction", "PhysicsChain.bounciness", "PhysicsChain.frictionMixing" or "PhysicsChain.bouncinessMixing".

• QNX: Fixed the player window not resizing when the resolution or fullscreen mode changed, which left the rendered content stretched or misplaced. (UUM-150071)

• Scripting: Fixed a console performance regression introduced by the virtual-memory EntityId allocator. EntityId (instance ID) allocation and release are significantly faster, especially under multithreaded create/destroy churn, and committed memory no longer grows under sustained object churn. (UUM-148756)

• Serialization: Fixed Analyzer UAC1016 error flagging a Dictionary with generic types as cannot be serialized incorrectly (UUM-155167)

• Timeline: Fixed an issue where property changes were not correctly re-evaluated in the the Timeline, after being added. (UUM-150294)

• Timeline: Fixed an issue where scrubbing the timeline while in recording mode could trigger additional graph rebuilds (UUM-150705)

• uGUI: Fixed crash when calling SetSecondaryTexture/Size with invalid index (UUM-154589)

• uGUI: Fixed RectMask2D softening the edges of clipped content when its softness is zero (UUM-150815)

• UI Toolkit: Fixed a USS file failing to import and losing all of its styles when a function such as linear-gradient() had an empty argument. (UUM-155939)

• UI Toolkit: Fixed an issue where a TextField displayed a replacement character when Max Length cut the text in the middle of an emoji. (UUM-155098)

• UI Toolkit: Fixed blank unit dropdown on Animation window Length rows. (UUM-148568)

• UI Toolkit: Fixed Panel Renderer fields not resetting when the component is reset. (UUM-154983)

• UI Toolkit: Fixed PanelRenderer not updating its parent PanelRenderer and visual tree when its GameObject was reparented at runtime. (UUM-154720)

• UI Toolkit: Fixed PanelRenderer not updating its parent PanelRenderer and visual tree when its GameObject was reparented at runtime. (UUM-154720)

• UI Toolkit: Fixed scaled elements looking blurry when a filter is applied to them. (UUM-155303)

• UI Toolkit: Fixed the content of a ListView or TreeView with horizontal scrolling moving horizontally when scrolling vertically. (UUM-147817)

• VFX Graph: Allow renaming a category changing only the capitalisation (UUM-151393)

• VFX Graph: Creating a property with a category name now works as expected instead of not showing the property (UUM-151382)

• VFX Graph: Fix "InvalidOperationException: Sequence contains more than one matching element" error thrown when creating a new Property with an existing attribute name (UUM-151379)

• VFX Graph: Fixed renaming a category will move its position to the end of the list when saving (UUM-151383)

• VFX Graph: Renaming a Category to a reserved name now logs an error message instead of failing silently (UUM-151381)

• VFX Graph: SDF baker: Prevent writing out of bounds past the triangleIDs buffer when a mesh exceeds the triangle list size estimate (UUM-152713)

• VFX Graph: SDF baker: Prevent writing out of bounds past the voxel grid when a mesh face lies exactly on the bake box boundary (UUM-152711)
