Hi MP, <> Do you mean unzipping the file you have attached? Also another general question: When should I use the "mapped picture" and when the " Procedural colors"? In other words what should i want to achieve by choosing one over the other. I know my own answer, but just want to make sure that I am on the right track. Also you say <>. isn't this "material" and the "picture" the same thing? Or are they two different files? You might have guessed that I have not unzipped your attached file yet. Thanks again for your help and patiently waiting for the response. Reagrds, Nick
