Zbrush is used for modling in conjunction with quite a few other applications. Mostly used for refinement of base models, but it\'s capable of creating any number of models, compatable with Lightwave, 3ds Max, maya, XSI, Lightwave, you name it. Can output in a number of formats, create meshes as tri or quads, can create bump maps, normal maps, displacement maps, color maps.... Was used in quite a few films including Lord of the Rings, and several others. Does wonders with details, however it\'s best used with out programs for composition. Still getting used to it, as you\'ve said it\'s not like most apps.
