Ahoy, I was just curious as to how I might change or add new skin tone colors, I have been looking at my unpacked textures and can't find it was hoping someone could point me the right way.

Have a look at the first post in the Video Tutorials thread. A guy has a great video to change an actors skin. He uses a rainbow chicken as an example.

Also a good way to use people's animal textures in your own mod, with permission to re-upload ofcourse
