No problemo!

Bill Fleming (who I like to call the William Shatner of 3D) in his heyday had a few good books out there, they're sorta hard to find now (except for used) and are typically highly recommended by those who have read them.

The Photorealism Toolkit ( http://www.amazon.com/3D-Photorealism-Toolkit-Bill-Fleming/dp/0471253464 ) was a very good book on providing tips on how to make your models and scenes more realistic. He was a big fan of the "chaos" concept.

If you can find a copy for sale, it's highly worth it!
