Honestly, I don't see anything wrong with this criticism and I agree that the teeth are too bright at times. I believe that
larsalexanderson is talking about Kendra's teeth in the banner image as far as being metallic. They're right - the teeth are too shiny and they look weird from the light reflection.
I hope that doesn't stop you from playing the game, because I promise there's a lot more in the game, good and bad, than the teeth being too bright. That kinda stuff happens in Daz, especially with the amount of content I'm putting out at the pace that I'm going. I just don't think it's worth spending a ton of time going back and fixing teeth. It is something that I try to work on going forward though.
