◆ EARFaceTrackingDirection

Enumerator
FaceRelative 

Blend shapes are tracked as if looking out of the face, e.g. right eye is the mesh's right eye and left side of screen if facing you

FaceMirrored 

Blend shapes are tracked as if looking at the face, e.g. right eye is the mesh's left eye and right side of screen if facing you (like a mirror)
