While I'm sure this is unintentional, if you have "Gloss/Shine" turned off... you also turn off teeth, which leads to situations like this:
Is there any way that can be undone, or are they too attached together at this point?
Okay... That was clearly unintentional. Pretty embarrassing, that was. We'll look into it right away. Thank you very much for your information!
I've actually found that while turning on Gloss/Shine brings the teeth back, for whatever reason, with this character the inside of her mouth is all black instead of featuring the usual that you see with other characters. It's quite odd.
