Oculus Developer Release Notes: v18/1.50

Oculus Integration for Unity

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

• Moved the shader stripping option in OVRManager.
• OVRManager requires Unity version 2018.3 or higher.

• 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.

• 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

• Updated Oculus master license for the Oculus Integration package.

Unreal Engine 4 Integration

• Added two new features to shorten the development cycle for Unreal:
• On mobile devices, you can shorten the deploy cycle by enabling the Deploy compiled .so directly to device (Oculus) setting. For more information, see Reduce App Deploy Time.
• Added a new build feature based on FASTBuild⁠ that uses distributed computers to reduce the compile time for Unreal Engine projects. For more information, see Improve App Compile Time.

• 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.

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.
