Facerig seems to think that the camera is to the top right of the model, and that normally i'm looking in the opposite direction to the camera, and there's no option that I have found to change this: I've uninstalled, verified files, reinstalled drivers for my webcam, done every feasible option in the game that I could do to try and fix it.

Here's a gif of it happening for you to see:

I hope this can be resolved soon.
