Variations in texture can be used not only in animating, but to get some nice mixtures in textures without having to merge 2 textures in a paint program. And, as I've shown here, it's very nice for any character that can change dramatically in an animation, like werewolves, vampires, Hulk-like morphing (can you say "Freak?"), and the Aeon figures that age. My next tutorial (in a day or so) will be how to convert clothing so it will have aging features compatable with the Aeon figures. It's actually pretty easy.
