	<brief_description>
		A tracked face.
	</brief_description>
	<description>
		An instance of this object represents a tracked face and its corresponding blend shapes. The blend shapes come from the [url=https://docs.vrcft.io/docs/tutorial-avatars/tutorial-avatars-extras/unified-blendshapes]Unified Expressions[/url] standard, and contain extended details and visuals for each blend shape. Additionally the [url=https://docs.vrcft.io/docs/tutorial-avatars/tutorial-avatars-extras/compatibility/overview]Tracking Standard Comparison[/url] page documents the relationship between Unified Expressions and other standards.
		As face trackers are turned on they are registered with the [XRServer].
