The best I've found are Gary Miller's at
Geek-at-Play, just takes a while to work through 'em (there's a lot of 'em - 87, I think); and of course
EZ's starter tutorials in the Hexagon Discussion boards at the Daz website (but I bet you already have those). I've been away from it, but want to get back. (Have been trying to get a grip on lighting in DS-3a these past few days, lol). Also, I've heard some good things about the
Hex tutorials at Polyloop, but haven't taken time to explore those. Hoping to be back to mashing cubes soon!
