Known issues

When the following conditions are met:

  • Oculus OpenXR is selected as the Play Mode OpenXR Runtime for the standalone platform, and
  • Initialize XR on Startup is checked for the standalone platform, and
  • The computer is not connected to a headset (via cable or wireless)

... Unity editor may frequently freeze in play mode. This is a Unity bug introduced in Unity OpenXR plugin 1.5. To work around this issue:

  • use a non-Oculus Play Mode OpenXR Runtime for the standalone platform, or
  • uncheck Initialize XR on Startup under Edit > Project Settings > XR Plug-in Management > Standalone while iterating in the editor via play mode, or
  • connect to a headset before entering play mode in the editor.

Breaking changes

  • The UX prefabs are now split into two packages: MRTK UX Components and MRTK UX Components (Non-Canvas)
    • Up until this point, our RectTransform-based (preferred) UX components were jumbled in with our non-RectTransform-based (static) controls, which caused confusion and frustration
    • Now the UX prefabs are separated into two packages based on their use of Canvas/RectTransform. This will allow for better clarity for developers.
    • Action item: if you're currently using any UX prefabs/components that aren't canvas-based, make sure you explicitly select MRTK UX Components (Non-Canvas) when updating in the Mixed Reality Feature Tool.
  • Changed the color space of the sample project to linear and adjusted materials accordingly
    • Optimized major UI-related materials and MRTK standard materials for use in linear color space. Their look in the gamma color space will be slightly different.
    • For more information on linear vs. gamma color space, see Unity's documentation.
  • CameraCache is now removed from MRTK in favor of Unity's performant Camera.main implementation
    • As of Unity 2020.2 (older than our minimum Unity version requirement for MRTK3), Camera.main has had some massive performance improvements!
    • Camera.main never took more than 0.0ms in in-editor profiler tests
  • Removed empty GazeController
    • All properties in this class have been deprecated. ArticulatedHandController provides equivalent functionality for each pinching hand.
