One more thing. I really like the shading tree. Took a while to get my head around it, but I am starting to like it. It offers an infinite number of ways to do certain things. Also, in the example above. Once I set the surface options for the first layer, I just "Ctrl dragged" a copy to the next layer. That way the initial reflection and highlight options were already set. Saves time. Then its just a matter of adjusting the colors.
