Hi folks, thanks for the responses. The solution I used was to put the shaders in the browser tray and reapply them to the books in my scene. For some reason I didnt think to just plop the books themselves in there. I ll try that with the sailboat, it will be a lot faster, because there are a lot of separate parts to which I would need reapply the shaders. Oh and I didnt try rendering to see if te error was limited to the assembly room or not. I might give it a shot before I fix the boat, just for the hell of it. Ill soon be ready to show you all my first Carrara image. Its simple but I think I did a decent job for a newbie. Cheers, Max
