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 [member 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. </description> <tutorials> <link title="XR documentation index">$DOCS_URL/tutorials/xr/index.html</link> </tutorials> <members> <member name="bone_update" type="int" setter="set_bone_update" getter="get_bone_update" enum="XRHandModifier3D.BoneUpdate" default="0"> Specifies the type of updates to perform on the bones. </member> <member name="hand_tracker" type="StringName" setter="set_hand_tracker" getter="get_hand_tracker" default="&"/user/hand_tracker/left""> The name of the [XRHandTracker] registered with [XRServer] to obtain the hand tracking data from. </member> </members> <constants> <constant name="BONE_UPDATE_FULL" value="0" enum="BoneUpdate"> The skeleton's bones are fully updated (both position and rotation) to match the tracked bones. </constant> <constant name="BONE_UPDATE_ROTATION_ONLY" value="1" enum="BoneUpdate"> The skeleton's bones are only rotated to align with the tracked bones, preserving bone length. </constant> <constant name="BONE_UPDATE_MAX" value="2" enum="BoneUpdate"> Represents the size of the [enum BoneUpdate] enum. </constant> </constants> </class>
