Oculus Developer Release Notes: v39

Introduced a major update to hand tracking that improves tracking quality and supports new scenarios such as fast movement, light hand-hand interactions, and partial occlusion. To learn more about what's new for hand tracking and to set up the latest version, see the Hand Tracking documentation.

The minimum API Level required for the application to run is now Android API Level 29.

Added experimental support for Unity's OpenXR plug-in.

Added new ShowUntracked to show a keyboard even if it is not physically present.

Added Symmetric Projection feature in the Oculus XR Plugin. It improves GPU performance when using Multiview and Vulkan on Quest 2.

Added Sub-Sampled Layout feature in the Oculus XR Plugin. It helps reduce visual artifacts with FFR when using Vulkan on Quest 2.

The Gestures sample demonstrates the use of the Sequence component for gesture detection.

PolylineGizmos utility enables drawing debug Gizmos in the game view and in the headset.

JointVelocity and JointRotation components are available for gesture detection.

Pointable and Grabbable items now share a common PointableElement interface. This enables interrupting pokes and transferring grabs with the Pointable Cancel event.

You can now send follow-up requests immediately following mic closing on a request.

Tracked keyboard and render model support can no longer be enabled if OpenXR is not enabled.

Hands no longer jitter excessively when the OpenXR backend is selected.

Finger flexion for hand pose detection is no longer affected by abduction.

Textures that appeared black in the sample scenes with the OpenXR backend enabled now appear correctly.

Requests would not run if app data was missing even if a client token was shared with the project. This was an issue for teams using version control for their projects.

Requests are properly aborted when no data is sent.

Fixed issues with the initial setup process with Voice SDK.

Better pinch and palm grabbing detection algorithms

Custom movement behaviors can now be configured to specify how grabbable objects should move towards grab interactors.

Improved editor UI around Understanding Viewer and wit configurations in Voice SDK

OVRManager.cpulevel and OVRManager.gpuLevel are deprecated. Instead, use ProcessorPerformanceLevel OVRManager.suggestedCpuPerfLevel and ProcessorPerformanceLevel OVRManager.suggestedGpuPerfLevel to get or set the performance level.

Oculus Avatar SDK (legacy) is removed from the Oculus Integration SDK. This means that the Avatar folder is no longer available in the Assets > Oculus folder. We strongly recommend that you adopt the Meta Avatars SDK instead of continuing the use of legacy Avatar. It is still available in previous versions of the Oculus Integration SDK but the documentation support will be removed eventually.

The Thumb0 bone pose does not pinch all the way and there is about a 1/8 of an inch gap between the index finger and thumb when using the system gestures.

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.

Fast movement or teleportation with Application Space Warp in Unity can have some artifacts.

PC XRSDK GetDominantHand crashes app. Workaround: Because of a limitation of Unity native plugin, accessing Oculus features through C# initializer could trigger crash on PC. If this happens, move the member initialization to Awake() or Start() functions.

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.

OVRPlugin updated to 1.71.0

Blueprints GetCPUandGPULevels and SetCPUAndGPULevels have been deprecated. Use GetSuggestedCpuAndGpuPerformanceLevel and SetSuggestedCpuAndGpuPerformanceLevel instead. For the highest sustainable CPU and GPU level, use Sustained High, not Boost.

Introduced a major update to hand tracking that improves tracking quality and supports new scenarios such as fast movement, light hand-hand interactions, and partial occlusion. To learn more about what's new for hand tracking and to set up the latest version, see Hand Tracking.

Leaving the passthrough component active should no longer cause flickering.

Developer Dashboard: Developers can use the developer dashboard release channels to manage debuggable builds. Developers can upload debuggable builds to any non-public channel in the developer dashboard.

A marketing attribution dashboard was recently added to help you track how effective your marketing efforts are. For more information, see Marketing Attribution Analytics.
