For what it's worth, I find Poser shaders to be terribly complicated and Luxrender's materials much less so, probably because there's much less to them ;o). Having said that, the procedural textures codes and things within Luxrender still befuddle me a bit, but no more than Poser shaders have in the past...lol. I'd love to start adding procedural bump and other things to textures now, but I have to get straight on how they're used first.
