Procedural materials are used in many other programs like Terragen, Darktree, Bryce, MojoWorld, yada yada. The nodal procedurals for P5 hardly different than those, but the interface is way different. I'd suggest you stay with P5 and do the tuts and I agree, there needs to be more in depth work on this. Susan Kitchen's, for example, wrote a 1000 page book on Bryce and a large portion of it deals with procedureal textures/objects. Nodal textures are the up and coming thing and after you get the concepts down, you'll be able to change apps and dive into the interface better. I think Darktree and Poser have the easiest of interfaces for this. Bryce is way easier but does so much for you that you don't learn much about how to hook up the nodes (unless you dive into the deep texture editor and the obscure rooms). Terragen which is a freeware also uses something similar to nodal deal but is less robuste. Mojoworld is nodal and quite complex. Electric Image Universe also uses a layered texture system that could be thougth of as nodal and there are a ton of video tuts on their site or the dvgarage site. I'd love to see someone take a sabbatical and put all this together in a good book. In fact, it may have been done already. I'll have to find the book again, don't have a link, but I recall a thread a few months ago about a book on procedural materials and it was supposed to cover P5 as well.
