Improvements

  • 2D: Change Outline and Physics Shape module behaviour in Sprite Editor Window. The module will only show outlines only when user has customised it.
  • 2D: TextureImporter Inspector has an option to enable default Physics Shape for Sprites
  • Linux: Improved filesystem performance to handle large cache sizes.
  • XR: Improved background rendering performance in ARCore by eliminating an unnecessary OpenGL state reset.
  • XR: Updated Oculus to version 1.22.

Changes

  • Asset Import: Adjusted messaging around Substance Designer import removal.
  • XR: Android builds that enable ARCore no longer fail when the minimum Android SDK is less than 24.
  • XR: Standalone UWP applications targeting Windows Mixed Reality will now cause the OS to notify the user if the Mixed Reality components are not installed or a headset is not connected, rather than silently falling back to non-VR desktop mode.
