Real World Bryce is "THE" only book that can really show you what Bryce is about. The tree lab and metaballs aren't covered but everything else is, and in great detail. I got my copy used from Amazon and the Disk that came with it hadn't even been opened. It is the only book I refer to when working with Bryce 'cos I've looked through others in book stores and they don't come close in quality or detail. Much of the theory behind the references can be applied to other 3D apps too. Stick with the best and you won't go wrong. 8) Catlin BTW, Susan Kitchens was talking about doing an update for Bryce 5 and was going to post it on her web site. I haven't been there for a while so I don't know if she's added it yet.
