I start with ZBrush for quick concept base on Mass Effect 3 and Mental Gear characters. After I've done my concept in ZBrush, I retopo every part with zsphere. Some of those parts are modified in 3ds max and add more detail. Rendering in mentalray with 3 main lights (key, fill, back) and some omni lights where i want more specular. Texturing in ZBrsuh and Photoshop. Thanks for watch and enjoy!!
