Version
209.0
The core interaction building blocks from the Interaction SDK in a lightweight, platform-independent package with no dependency on the Meta XR Core SDK. Provides the foundational framework for grab, poke, ray, and locomotion interactions, along with hand pose detection tools and visual indicators. The Essentials package does not include any Meta-specific dependencies and is designed to work across platforms.

Version 209.0 Release Notes

What's New

Hands Debug Overlay


We added the DebugInputView prefab, which displays an overlay with the state and logs of OS-provided hand gestures, including pinch and microgestures. For pinch, the overlay shows the current state and pinch strength of the index and middle fingers on each hand. See the Hands debug overlay documentation for more information.

OS-Style Panel Transformer


We added the OSPanelTransformer, which moves panels the same way the system UI does. The panel smoothly tracks the user's head and retains its angular size as it moves closer or farther away.

What's Fixed

  • Fixed FindObjectsByType calls that were incompatible with Unity 6.4 and later.
  • Fixed per-frame allocation in GazeInteractor by reusing the same GazeCandidateProperties object every frame. Copy the properties if you need them beyond the current frame.
  • Fixed a 40-byte per-frame allocation in RayInteractor by reusing the same RayCandidateProperties object. Copy the properties if you need them beyond the current frame.

    • Improvements

  • Added the standard Interaction SDK hover effects to the 3D objects in the GazeExamples scene.
