  • UUM-104889 DirectX12: [Intel] Crash on BufferD3D12::BeginWrite when opening a newly created URP project with DirectX12 set as the default graphics API
  • UUM-125284 IL2CPP: [iOS] [Android] External library generics fail during IL2CPP build
  • UUM-128966 Mesh: Crash on SkinnedMeshRendererManager when interacting with a prefab generated with uncombined meshes using Synty Sidekick Character Creator
  • UUM-125778 Metal: Game freezes after command buffer Timeout error

  • ### 6000.0.64f1 Release Notes

📈 Improvements

  • UUM-117415 AI: Improved performance of sampling the nearest position on the navmesh.
  • UUM-119638 Documentation: Reformatted the documentation page for "Cubemap.CreateExternalTexture" and added missing information. Corrected expected pointer type for D3D12 on all "CreateExternalTexture" pages \(always "ID3D12Resource*"\). Minor polish pass on the page for "Texture3D.CreateExternalTexture", no actual changes in content outside of the mentioned D3D12 change.
  • UUM-97524 Editor: Improved interactivity of progress bar when opening the "Compile and Show Code" dropdown in the Shader Inspector.
  • UUM-127566 Editor: Minimum width of the Sprite Editor Window has been increased so when the window is undocked it cannot be resized so that the window is too thin to display all the buttons on the toolbar.

🔄 Changes

  • Multiplayer: Removing references to Multiplayer Widgets from documentation after deprecation of package.

🔧 Bug Fixes

  • UUM-125625 2D: Fixed issue where the user sees an error dialog after cancelling a SaveFolderPanel action from the Tile Palette.
  • UUM-104008 2D: Fixed LIght2D toggle UI.
  • UUM-125376 2D: Sprite Editor Window Custom Outline and Physics Custom Outline inspector window is disabled when in playmode.
  • UUM-78535 Android: Fixed crash that could happen during configuration changes on Android.
  • UUM-120998 Apple TV: Fixed On Screen Keyboard closing when typing with a controller or Siri Remote.
  • UUM-107892 DX12: Fixed broken `IDXGISwapChain::GetFrameStatistics` with cpu-side time sampling.
  • UUM-128283 DX12: Fixed unrelated crash info that gets accumulated in the logs after a first GPU device crash. Now we shut down the app as early as possible after a DX12 crash, so that log messages, callstacks and DRED outputs are only relevant to the original GPU error.
  • UUM-117177 Editor: Fixed a bug that was causing an exception in the console when asset bundles containing terrains created by an older version of Unity were loaded that contained instanced terrain details.
  • UUM-127936 Editor: Fixed a bug where accessing an overlay's containerWindow could throw a NullRef Exception.
  • UUM-116317 Editor: Fixed a bug where the Reflection Probes Gizmos could disappear in the Scene View.
  • UUM-88043 Editor: Fixed an issue where the mesh would not update on the first undo in TreeEditor.
  • UUM-128238 Editor: Fixed artifact in bitmap IMGUI text.

  • UUM-115985 Graphics: Fixed missing documentation link for the Lens Flare \(SRP\) component.
  • UUM-125992 HDRP: Fixed FSR2 quality setting not applying when changed from the camera using 'Use Custom Quality' property.
