Unity

What's new in this version:

Fixes:
- Animation: Fixed-Multiple warnings are thrown when loading a Scene with PlayableGraph playing
- Asset Import: Changed ProcessAssetBundleEntries() to batch load assets using PersistenceManager rather than loading individually using PPTRs
- Asset Import: FBX importer address issue where an object animated visibility was turning to invisible if parent of object was animated only for a sub-section of the child animation range.
- Asset Import: Fix for case 1232463 - NullReferenceException thrown when selecting multiple model assets and having the animation tab open
- Asset Import: Model importer was preventing the user from re-extracting textures
- Asset Import: Significantly reduces import time of FBX models, particularly for those containing large meshes.
- Asset Pipeline: Corrupted assets are cached and causes cache poisoning
- Editor: Apply changes in Inspector correctly
- Editor: Fix OnPreviewGUI method's background image is rendered grey instead of white when background image is set to white texture
- Editor: Fixed EditorApplication.isPlaying is true in the first OnDisable() when entering Play mode with Play Mode Options enabled
- Editor: Fixed potential graphics device resource leak when triggering long synchronous build tasks
- Editor: Fixed the background image of popup windows in active state
- Editor: fixes an issue where smart rounding was causing problems with large scale values with the Rect tool
- Editor: Modal windows don't allow interaction with other windows until they are closed(affects EditorWindow.ShowModal() and EditorWindow.ShowModalUtility())
- Editor: Removed Entering Playmode with Reload Domain disabled message from a console window
- GI: Fixed an issue with normals during bounce calculations in the GPU lightmapper, leading to large differences in brightness between the CPU and the incorrect GPU lightmapper.
- GI: Fixed issue where clamp method was used wrongly.
- Graphics: Correctly clear a render target before a compute pass
- Graphics: Fixed memory leak when disabling texture mip streaming (after enabled)
- Graphics: Fixed PS4 error, thrown when SkinWeight is set to more than 4 bones per vertex.
- Graphics: Further fixes for loading 17.4 asset bundles in to later versions of Unity
- Graphics: Mesh Yaml content could no longer be parsed properly leading to unitialized VertexBuffers causing crash.
- Graphics: Removed some unnecessary warnings
- Graphics: Shader.WarmupAllShaders() no longer submits a shader that uses VK_EXT_shader_viewport_index_layer without enabling it in context creation.
- iOS: Copy across referenced images from the launch screen storyboard during build times.
- iOS: Fixed crash when trying to use metal on simulator (this is supported starting with unity 2020.1)
- iOS: Screen.SafeArea should be reported correctly after the app is paused and it's orientation is changed.
- iOS: Screen.SafeArea should no longer reset to zeros after custom view is presented on iOS 13.
- macOS: Fixed crash when running macOS editor in batchmode with no display attached
- Particles: Fixed particle lights being re-rendered over multiple frames
- Physics: Fix an issue where a BoxCollider2D with an EdgeRadius > 0 resulted in "Physics2D.queriesStartInColliders" being ignored.
- Physics: Fix Physics.BakeMesh() not being able to reuse the same Mesh again
- Prefabs: Fix: Error is thrown when moving components up/down in Prefab variant after pressing "Open Prefab"
- Profiler: Reduced memory usage and optimized Timeline View generation in Profiler Window.
- Scripting: Avoid allocation in Enum.HasFlags
- Scripting: Fixed possible crash caused by race condition during startup when the script debugger and profiler systems are enabled.
- Scripting: Handle accessing unloading domains inside the debugger.
- Serialization: Fix error where OcclusionData yaml file parsing was no longer working.
- XR: CPU affinity detection was incorrect on 64-bit mobile Oculus builds. This affected how many worker threads were created
- XR: Fix for excessive XR Shader Build times when buliding Player on Android
- XR: Fix remoting return codes when connecting fails

Improvements:
- Editor: When a compile error is emitted for an assembly, clear all compile errors for all assemblies that reference it directly or directly. This improves workflows when dealing with compile errors, as fixing an assembly's compile errors might also fix compile errors in any assemblies that reference the assembly directly or indirectly.
