Oculus Integration for Unity

New Features

  • Use customized XML to define security configuration for Android instead of using Oculus-generated XML.


Bug Fixes

  • Added support to trigger the RecenteredPose event in stationary experience or when there's no guardian set up.

  • Fixed the return value for the GetHmdColorDesc() method to Unknown for macOS or any other unsupported platforms.

  • Fixed in-Editor MSAA setting forced off when using XR Management.

  • Fixed a race condition in which bone pose updates are retrieved before the mesh is bound to the skeleton causing issues with the appearance of the skinned mesh component.

Integration Changes

  • Ended support for Unity version 2017.4. The minimum supported Unity Editor version for Oculus development is 2018.4.

  • Updated the Oculus Unity Integration package to v18.0, including:

    • Updated OVRPlugin to 1.50

    • Updated the Audio Spatializer to 18.0

    • Updated the Platform integration to 18.0

    • Updated the Avatar integration to 18.0

    • Updated the LipSync integration to 1.43

License Update

Unreal Engine 4 Integration

New Features


  • Added an error that displays when Support Vulkan is checked in Android platform build settings and the Oculus target device is an Oculus Go.

  • Optimized the splash screen to display earlier in the loading cycle and work as expected.

  • For mobile, cleaned up XML tags in the manifest and fixed an issue with the focus-aware tag not being added for disabled situations.

  • Mobile : Saved ~100Mo (Vulkan), ~30Mo (OpenGL) of GPU RAM by removing a backbuffer allocation, merging MobileMultiviewSceneColor with SceneColor (same for depth), and not creating the non-MSAA shader resource for depth buffers.

  • Mobile : Saved ~0.5s of startup time by enabling stereo on the first frame, initializing sRGB flag to true, and requiring MSAA to be set in project settings instead of auto-set. See the Quickstart for this setting.

  • For mobile, added MSAA to the list of performance widget checks. See Oculus Performance Settings for more information.

In addition, there are numerous bug fixes. For detailed release notes, see the Unreal Engine 4 Integration Release Notes.

Platform SDK

  • This is a maintenance release with bug fixes and performance improvements.

Avatar SDK

  • This is a maintenance release. There are no developer-facing changes in this release.

Mobile SDK

  • A new ovrLayerType flag, VRAPI_LAYER_TYPE_EQUIRECT3, and corresponding structure ovrLayerEquirect3, have been added to the API. This allows specification of an equirectangular texture with a non-infinite radius at a specific location.

  • The ovrSystemStatus type, VRAPI_SYS_STATUS_DOCKED, has been deprecated and removed from the API.

  • The ovrSystemProperty type, VRAPI_SYS_PROP_EXT_SDCARD_PATH, has been deprecated and removed from the API.

Audio SDK

  • Maintenance release that contains bug fixes and performance improvements.
