Hi,
I am trying to use the VisemeDriver component from the Meta XR Movement SDK and Meta Quest Pro, but visemes never update. I have enabled the face and visual input in OVRCamerRig, and have enabled the viseme in OVRCameraRig, I also enabled the experimental features and “Record Audio for audio base Face Tracking”.
After debugging, I found that OVRPlugin.GetFaceVisemesState always returns Failure_Unsupported, which causes:
OVRFaceExpressions.AreVisemesValid = false
As a result, the VisemeDriver Update() method never runs.
Face expressions work correctly, but visemes are never available.
Relevant log output:
FaceTrackingEnabled = True
ValidExpressions = True
VisemeResult = Failure_Unsupported
AreVisemesValid = False
