XRFaceTracker
=============

**Experimental:** This class may be changed or removed in future versions.

**Inherits:** :ref:`XRTracker<class_XRTracker>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A tracked face.

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

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

An instance of this object represents a tracked face and its corresponding blend shapes. The blend shapes come from the `Unified Expressions <https://docs.vrcft.io/docs/tutorial-avatars/tutorial-avatars-extras/unified-blendshapes>`__ standard, and contain extended details and visuals for each blend shape. Additionally the `Tracking Standard Comparison <https://docs.vrcft.io/docs/tutorial-avatars/tutorial-avatars-extras/compatibility/overview>`__ page documents the relationship between Unified Expressions and other standards.

As face trackers are turned on they are registered with the :ref:`XRServer<class_XRServer>`.
