This is a character I made recently, largely for practice and to develop a nice workflow integrating sub-d modelling in Max, detailing in zBrush, and texturing with procedural textures plus zBrush and photoshop painting. He is based on a character sketch by the excellent James “Hawkprey” Hawkins.
The central idea behind the workflow is building hi-res models suitable for being baked down to game-res or cinematic res, with additional texture work done once the model has been baked down. See the AVI of his weapon for an example of a completed game-res weapon with a finished texture.
