	<brief_description>
		A node for driving body meshes from [XRBodyTracker] data.
	</brief_description>
	<description>
		This node uses body tracking data from an [XRBodyTracker] to pose the skeleton of a body mesh.
		Positioning of the body is performed by creating an [XRNode3D] ancestor of the body mesh driven by the same [XRBodyTracker].
		The body tracking position-data is scaled by [member Skeleton3D.motion_scale] when applied to the skeleton, which can be used to adjust the tracked body to match the scale of the body model.
