Oculus Developer Release Notes: v33

Oculus Integration for Unity - v33

• OVR Build APK now supports selecting the location of your built APK, generating release builds, and saving keystore passwords.

• A crash that occured on start in an MRC-enabled app when the Unity splash screen is turned off in the OpenXR backend
• OpenXR compatibility issue with haptics on the v32 OS release
• A crash that occured when using OpenXR backend on Oculus Link
• Clamp to edge artifacts appearing on compositor layers
• OpenXR compatibility issue with haptics on the v32 OS release

• OVR Build and Run APK now supports production build and not just development or debugging build

• Support for hand-tracking is currently restricted to the baseline OpenXR spec. Therefore, additional hand-tracking features such as collision capsules, hand input metadata, and runtime hand meshes are not yet supported. In addition, there is a known compatibility issue with the thumb trapezium bone (Thumb0) in the OpenXR-based OVRPlugin. Due to the known compatibility issues with hand-tracking and haptics, Oculus Store and App Lab will not accept apps built with v31.x SDK and OpenXR backend.Workaround: Hand tracking features are fully functional with the legacy VRAPI backend. If you want to submit apps to Oculus Store or App Lab, you must switch to the legacy backend. In the Unity editor, go to the Oculus > Tools > OpenXR > Switch to Legacy OVRPlugin menu to switch to the VRAPI backend to continue using hand tracking features. Find detailed information in the Switch between OpenXR and Legacy VRAPI documentation.
• Mixed Reality Capture on Rift is not supported in OpenXR. Workaround: In the Unity editor, go to the Oculus > Tools > OpenXR > Switch to Legacy OVRPlugin menu to switch to the VRAPI backend to continue using Rift MRC. Find detailed information in the Switch between OpenXR and Legacy VRAPI documentation.
• GetAppPerfStats and ResetAppPerfStats are currently not supported with the OpenXR backend. Workaround: In the Unity editor, go to the Oculus > Tools > OpenXR > Switch to Legacy OVRPlugin menu to switch to the VRAPI backend to continue using Rift MRC. Find detailed information in the Switch between OpenXR and Legacy VRAPI documentation.

• Changing modes in Lipsync_Demo on Oculus Quest is currently not supported.
• If you're using the Spectator Camera feature and you switch the view, the casting video is flipped upside down. Workaround: Set SetMrcFrameImageFlipped to false. For more information, see the Known Issues section in the Spectator Camera user guide.
