It covers everything you need to create models of all kinds for your game projects, even if you've never used ZBrush before.Built around four complete ZBrush projects, the book gives you everything you need to sculpt props, vehicles, and creatures in ZBrush. You'll start by creating a "spooky tree" model, mastering the sculpting, texturing, and decoration skills that are essential for all ZBrush topics. Next you'll move to man-made objects with a sci-fi drone. Next you'll see how to sculpt monsters and other creatures, deal with cloth and other soft materials, and prepare the model to become an animated, controllable character in a game.
