Hello, sorry this is so long after the post but if you are still around I am having the same issue as the person here was. I'm not particularly new to KOTOR mods but I'm struggling to figure out what you mean here as I'm kind of a noob at modding. I need to change my appearance.2da from default to baremetal like you said but I don't know how to edit it. Is this something you can only do with the KOTOR tool? I've not used it much. I need to make my Darth Revans maskless robes not be transparent in the chest. Thanks!
After more research I think what I need to do is get the kotor tool, go to appearance.2da, change the envamp from default to baremetal, but that this may affect other things that are supposed to be transparent, which I don't want. Hopefully this is correct, I don't want to mess my game up. If you have time to respond am I on the right track?
