Gumroad - Intro to ZBrush Part 2 by Michael Pavlovich

With almost 8 hours of instruction and 70 videos, Intro to ZBrush Part 2 is designed to crank your ZBrush abilities up a notch! We start immediately with getting custom hotkeys, interface, and menus to keep your creativity flowing on the page, instead of hunting and pecking off to the side. From there we'll give your designs a boost, with base mesh, accessory mesh, and advanced brush creation techniques. To wrap it up, there will be bonus videos on how the cover art to ZBrush Part 2 was created.
