well that was really interesting, wingnut. I wonder if it'll work in Carrara, otherwise I'm going to play with it tomorrow in Hexagon. I wonder if it will do it numerically as well.

Thank you for that tip.

To present my credentials, this is a sample of what I show to clients. Criticism is welcome - it always helps.

This was done with a single back light, a fill light on the backdrop and a side light. No reflectors, no diffusers and no soft boxes. I know the glare on the cap is a bit too much - I'll do it again at some point. And the round halo on the front may get edited out in Photoshop, but it isn't really necessary.

For me carrara's photorealistic rendering is really up to scratch. Just takes a bit of effort to work out the logic of the shaders in real world terms...
