This demonstration is a four hour timelapse of the entire making of the African Woman by Rick Baker. There is no audio. Rick begins with a simple humanoid torso basemesh from which he sculpts the woman. The final result consists of several subtools that originate from mesh extractions. The demo is made with Zbrush 3.0 beta, therefore the interface looks a little different from the final release.
Vol1: Materials are a critical element in 3D. The shape of any object is altered by the shape perception added by the material. In other words, you can make the best looking terrain or scene, but without quality materials it will lack dramatic visual appeal.
