Thanks to all for the fast feedback. I will try all those techniques very soon. I have to finish some traditional 2-D freelance projects before I get my hands back into my 3-D projects. I've mostly been a silent participant for a few months reading all the postings at this site but I wanted to say thanks to all, it is a very helpful and very inspiring place to gather info for Carrara. I also wanted to say thanks to litst, I believe you are the creator of Real World Metals. Not only has this shader pack helped numerous images I have worked on but disecting the shader trees has helped me to understand better how the Carrara shaders work so I can create my own shaders. Again - many thanks memaci
