3dbuzz has released it’s first ZBrush training videos at www.3dbuzz.com. The VTM isn’t complete yet, but he’s posting the parts as he finishes them. You can read more about it here: http://sv2.3dbuzz.com/vbforum/showthread.php?s=&threadid=15894
Pretty basic so far, but, knowing buzz, it’ll get advanced pretty quick.
The VTMs (Video Training Magazines) are completely, 100% free. buzz will even mail the cds to your door (for free) if you don’t have the bandwidth to download them. So far, I’ve received VTMs for Maya, max, Photoshop, PHP/MySQL, and others. I downloaded the ZBrush one today. Incidentally, Pixologic is one of 3dbuzz’s sponsors.
