The August 2007 3D World Magazine has some interesting headline articles.
Chris Bullen looks at realistic interiors and Pete Draper returns to the badlands. But the one that will be making me get a copy is Matt Roussel's rendering technique to simulate clay. The turorial looks at both texturing and lighting this style using Cinema 4D. It will be interesting to see how it looks compaired to my attempts and programmes like the Island of Innis Cool.
