What I really enjoy about this forum is the things that are shared and posted that I never would have thought of by myself. Quite a few posts back, Litst posted the beginnings of an eye type of shader. We went back and forth making suggestions and showing results on how to improve the results. Well, the one in the Free Stuff section is what I came up with in the end. Man, I get a lot of inspriation from this forum. People post questions or an image and I think, "Now how would I do that?" Then I sit down and mess around for awhile. Mark
