ShaderMan v1 (old one)
What is ShaderMan?
ShaderMan is the visual Renderman shader building tool, made in spirit of ShadeTree, Slim and XSI, now superceded by ShaderMan.Next. This page is left here for history.
Presentware. This means: if you really like ShaderMan or you're earning something using ShaderMan and would like to thank the author for his work, you can buy him a present (book from his Amazon wish list). This isn't required, however. And this doesn't set any obligations to author. Consider this just as a gift.
