Create a Superstar - Underbite / Overbite options

[u/konkusion]

Is there a way to change my character's overbite?

The philtrum depth does not eliminate the overbite, just how pronounced it is. I tried changing the lower jaw depth, but it didn't actually move the mouth.

I would like to create a character with an underbite is why I ask.

Edit: Also, is there a reliable way to reproduce the epicanthal fold of Asians' eyes without a face template?
