Version
78.0
Meta XR Core SDK provides the latest features to create immersive experiences for Meta XR devices.

Version 78.0 Release Notes

The Meta XR Core SDK package contains core assets and features to help you create immersive experiences for Meta XR devices. This package is equivalent to the VR folder within the pre-existing Oculus Integrations package.

See the Unity Getting Started Guide for information about how to get started developing for Meta Horizon with Unity, or the Scripting Reference for a detailed API reference.

What's New

  • Audio To Expressions supports a new mode which supports Oculus Viseme-based blendshapes. This allows characters that were previously rigged with Oculus blendshapes supported by the Lipsync library to be directly supported by A2E with no re-rigging or blendshape conversion needed.

    • Known Issues

  • Compositor layers from the Unity XR Composition Layers package will disappear when used with the Meta XR Feature. This issue will be fixed in the next release.
  • In sample scenes, when using Unity’s new input system, the standalone input module in the “EventSystem” will not function correctly. To fix this, select the EventSystem game object and click “Replace with InputSystemUIInputModule” in the inspector.
