Same boat too. I’ve had less than enthusiastic results with ZSpheres myself, and to be honest it’s not for lack of understanding or trying (and yes, I’ve watched the tutorials included with ZBrush plenty of times). Also, Aurick mentions not letting link spehres go through each other, but I’ve seen a lot of examples over the past year here where the artist has done exactly that with great results, so the comments confuse me. I keep telling myself it’s all about practice and some day I’ll get it right, but so far it’s been a much more difficult nut to crack than, say, modelling a head out of a sphere tool or creating an object from an alpha.
