i was wondering what would be the best pattern or texture if uses adobe photoshop to use if u want to change say darth maul's face from the black and red skin tone to a normal skin tone. i am having a little trouble finding the right texture to reskin a head or body itself.

Darth Maul's face? Maul isn't in KotOR, so it's no wonder you can't find any textures. If you're talking about a mod, textures for those aren't found in KotOR tool.

the darth maul was an example. what i mean is that the photoshop u use for different textures to reskin an item for example a new suit of armour(different color or texture of the armour). i am wondering if there is a texture for the skin of a human that would have the details of the face or body structure and the shadowing and the curves of the human body where i can just use that texture and apply it on the item u want to reskin and the shadowing and details of the face or body will not be messed up.

A texure like what you're looking for would require every skin .tga to be laid out exactly the same so the shadows and everything line up correctly. I dont think what your asking for is possible :/

well it was worth a try thanks for the help anyway
