In questioning how to accomplish several modeling issues (if you can call them that), primarily surrounding how to create good hair for character models I was recommended the book Character Modeling 2 from the d'Artiste collection. I wish I had seen this earlier since it seemed to have the process behind modeling all of the gears characters, which are the zenith, or at least the standard, of character modeling at this point. It is now officially on my Christmas list. It will be mine, oh yes... it will be.
