Can you create a layered shader in PhotoWorks? Layered shaders are shaders that you can stack one on top of the others, with all but the bottom shader having to have some amount of transparency. Attached is a rendering of a bottle I did in Alias Studio. I was able to create the oily colored effect with layered shaders and the procedural maps that it has. I would really like to know how to do this in Photoworks.
