Thanks for the quick reply. I was able to get it to work and all I can say is "Wow." I tried it on plain ol' Don and even there it made an amazing difference. Two things. In the tutorial it suggests saving the node setup as a material and you suggest editting the .mtl file. Would saving the node setup as a material generate an mtl file? If so how do I save it? (I'm guessing the mtl will be a text editable file.) If not, what is the difference and how do I do that?
