Sorry I'll update the OP, I have a mod to use Carth's appearance/head as a possible choice for the player character in KOTOR2.
I also have a re-texture mod for Carth from KOTOR 1 I want to use in KOTOR 2. I realize the games are somewhat different so it wasn't likely to work, but when I place the texture mod in the override folder for KOTOR2 it only partially works. It changes his portrait but not his actual appearance like in the First game. So I was wondering if anyone had any insight about what I could possible do to make it work in KOTOR 2.
