Nope incandence, is just to add a under tone in a sence to the base color you applied. Same with ambient color. If you think of skin it's not just pink and orange it has tones of blue, red and green.... I added a fractal just to break up the green a bit and to give the skin a little bit of a vein look...
Im still not that good at it but i've seen some awsome skins done that way..... I could have just took pictures of my face from a few different angles and use that but I want to get good at painting and making my own before I take the easier way out...
