Oculus Developer Release Notes: v38

Oculus Integration for Unity - v38

What's New

• Late latching can now be enabled from the Inspector tab

• Added a curved Unity canvas sample in the Direct Touch sample scene
• Direct Touch (Poke Limiting) can now be used with curved surfaces rather than being limited to planar surfaces

What's Fixed

• OVRPlugin can't be loaded on certain CPUs that do not support AVX2 instructions
• OVRControllerPrefab will show Quest 2 Touch controllers properly when using Oculus Link
• Fixed space warp app space delta pose being one frame off causing artifacts during teleporting

• HandVisualEditor correctly shows joint mapping
• Editor component selector (InterfacePicker) correctly handles components with multiple interface requirements
• Fixed a race condition that could turn an empty selection into a hover
• Fixed a race condition with OnTriggerStay being called before _started

• Fixed deadlock caused by bad connection to servers.

Improvements

• Clamped the CPU & GPU level to 0-3 and avoided log spamming when invalid value is set repeatedly with the OpenXR backend
• Improved app performance on Quest 2 when input focus is lost with the OpenXR backend

• Grabbable replaces Transformable. You can now interface with a Grabbable component directly via its public interface. An InteractableTransformableConnection is no longer required for GrabInteractables or HandGrabInteractables.
• Multiple curved UI canvases can now be displayed on a shared cylindrical surface
• Interactor now implements IInteractorDriver. By default, there is no need to add InteractorDriver to the scene for any interaction to work.
• Curved UI canvases can now be oriented on a horizontal cylinder as well as a vertical cylinder

• Improved Voice SDK editor
• Improved threading around WitRequests
• Added support for tag parameter

Deprecation

• Multiple component renames - See the migration notes for full list of renamed components.
• SnapPoint is removed. Instead, use Tween as shown in GrabInteractor or HandGrabInteractor to achieve the same results. Refer to the ComplexGrab sample to see this capability in action.

Known Issues

• 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.
Workaround: Move SetAppSpacePosition/SetAppSpaceRotation to LateUpdate to guarantee that all movement logic has been run before sending new app space pose to the XR plugin.

• 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.

Unreal Engine 4 Integration

• Unreal 4.27 (Latest) ⁠

• Vignettes have been added to the tone mapping effects implemented as performant Vulkan subpasses.

What's Fixed

• PSO cache collection system now correctly collects all PSOs.
• In multiview, the pre-exposure values are now used correctly by both views.
• NiagaraRibbon opaque particles no longer exhibit screen corruption.
• When more than three passthrough layers are in use, submitting a failed layer no longer crashes passthrough.
• OVRLayers are now properly destroyed in GLES and no longer leak.
