Reference guide for the hand tracking Blueprints available through UOculusXRInputFunctionLibrary in the OculusXRInput module of the Meta XR Plugin. For a conceptual overview of hand tracking capabilities, see Hand Tracking in Unreal Engine.
For higher-level hand interactions such as grab, poke, and ray, consider the Interaction SDK, which builds on top of these Blueprint functions to provide standardized interactions and gestures.
To access these Blueprints, enable the Meta XR Plugin in your project and configure hand tracking support in Edit > Project Settings > Plugins > MetaXR by setting Hand Tracking Support to Controllers And Hands or Hands Only. The legacy Online Subsystem Oculus plugin is not required for hand tracking; that plugin provides platform and social features.
