Body Joint Visual Reference for Movement SDK for Unreal

• Animation node: The OculusXR Body Tracking animation node runs on the animation thread and maps body joint data to skeleton bone names. For setup instructions, see Animation blueprint for body tracking.
• Actor component: UOculusXRBodyTrackingComponent extends UPoseableMeshComponent and maps each EOculusXRBoneID value to a bone name through the BoneNames property. It applies joint transforms to the target mesh at runtime.

Note: The 70 body joints listed below cover upper body tracking (EOculusXRBodyJointSet::UpperBody). Full-body tracking adds 14 lower body joints (indices 70-83) through EOculusXRBodyJointSet::FullBody. Body tracking is supported on Meta Quest 2 and later (Meta Quest 2, Meta Quest 3, Meta Quest 3S, and Meta Quest Pro). For a complete working implementation, see the Unreal Movement sample⁠.
