This node uses hand tracking data from an XRHandTracker to pose the skeleton of a hand mesh.
Positioning of hands is performed by creating an XRNode3D ancestor of the hand mesh driven by the same XRHandTracker.
The hand tracking position-data is scaled by Skeleton3D.motion_scale when applied to the skeleton, which can be used to adjust the tracked hand to match the scale of the hand model.
BONE_UPDATE_FULL = 0
The skeleton's bones are fully updated (both position and rotation) to match the tracked bones.
BONE_UPDATE_ROTATION_ONLY = 1
The skeleton's bones are only rotated to align with the tracked bones, preserving bone length.
BONE_UPDATE_MAX = 2
Represents the size of the BoneUpdate enum.
Specifies the type of updates to perform on the bones.
The name of the XRHandTracker registered with XRServer to obtain the hand tracking data from.
