Something is wrong with Passenger as of late, I don't know what changed. The nose and mouth is still being rendered, while teeth are being removed from view. It doesn't make any sense.
@Eonyte Check out https://hub.virtamate.com/resources/embody.6513/ it's the successor or Passenger, it has all the same features and more, and a LOT of fixes! You can also save the Passenger mode as your default profile so every time you add Embody it'll be in Passenger mode by default
