================

**Inherits:** :ref:`SkeletonModifier3D<class_SkeletonModifier3D>` **<** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

A node for driving hand meshes from :ref:`XRHandTracker<class_XRHandTracker>` data.

.. rst-class:: classref-introduction-group

Description
-----------

This node uses hand tracking data from an :ref:`XRHandTracker<class_XRHandTracker>` to pose the skeleton of a hand mesh.

Positioning of hands is performed by creating an :ref:`XRNode3D<class_XRNode3D>` ancestor of the hand mesh driven by the same :ref:`XRHandTracker<class_XRHandTracker>`.

The hand tracking position-data is scaled by :ref:`Skeleton3D.motion_scale<class_Skeleton3D_property_motion_scale>` when applied to the skeleton, which can be used to adjust the tracked hand to match the scale of the hand model.

Enumerations
------------

.. _enum_XRHandModifier3D_BoneUpdate:

.. rst-class:: classref-enumeration

enum **BoneUpdate**: :ref:`🔗<enum_XRHandModifier3D_BoneUpdate>`

.. _class_XRHandModifier3D_constant_BONE_UPDATE_FULL:

.. rst-class:: classref-enumeration-constant

:ref:`BoneUpdate<enum_XRHandModifier3D_BoneUpdate>` **BONE_UPDATE_FULL** = ``0``

The skeleton's bones are fully updated (both position and rotation) to match the tracked bones.

.. _class_XRHandModifier3D_constant_BONE_UPDATE_ROTATION_ONLY:

.. rst-class:: classref-enumeration-constant

:ref:`BoneUpdate<enum_XRHandModifier3D_BoneUpdate>` **BONE_UPDATE_ROTATION_ONLY** = ``1``

The skeleton's bones are only rotated to align with the tracked bones, preserving bone length.

.. _class_XRHandModifier3D_constant_BONE_UPDATE_MAX:

.. rst-class:: classref-enumeration-constant

:ref:`BoneUpdate<enum_XRHandModifier3D_BoneUpdate>` **BONE_UPDATE_MAX** = ``2``

Represents the size of the :ref:`BoneUpdate<enum_XRHandModifier3D_BoneUpdate>` enum.
