A field that accepts a mouth tracking source (like DataSource on the Avatar Expression Driver Component) to assign a tracking source to.
Behavior
This component is triggered when a user equips an avatar that has this component as part of the hierarchy. The user that equipped the avatar needs to have an active mouth data source on their client, such as a Vive facial tracker, or using a mod that creates a source for mouth tracking (like VRCFTReceiver)
Examples
This can be used to assign the mouth tracking source on a Avatar Expression Driver Component to enable facial movements on an avatar via facial tracking.
