I'd like to thank you all for your positive comments on the Windigo. A couple of you mentioned that all of parts look like they "do something", and that is correct. This model has its origins in a sci-fi story written by a good friend of mine in which the ship is described in detail. I got a good mental snapshot of the vessel and was able to reproduce it in RDS. To Pleiades specifically, I like the image you posted. Where did that great marble shader come from? And you mentioned that you're using Corel 10 - have you used versions five through eight? They came with a program called CorelDream which was my introduction to raytracing. It was a super-stripped down verions of RayDream 3D, but it was a great program to get started in. Thanks again to all, Julian
