like @Masscot said... in CM you can create a skin.I know that, but I don't know how to get the original textures to edit other than using the 3dSimED program. It puts all the textures in a temp folder so it's easy to edit the ones I want to edit. If there is another way to extract the textures from a .kn5 file, i'm all ears cause i'm kind of new to this stuff.
When you do this:
1. CM will extract the textures and you select which ones you want
2. Name and create skin.
3. Goto named skin folder and edit textures.
4. Apply skin
5. Test in game
6. Enjoy how clever you are
