XRHandModifier3D

Inherits: SkeletonModifier3D < Node3D < Node < Object

A node for driving hand meshes from XRHandTracker data.

Description

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.
