I can't say enough about Schlabber's Poses. I was fortunate enough to download the entire contents of Posing is an Art. I won't be fortunate enough to buy his new CD for a time. I can't help notice there seem to be two versions of most poses: 1.) Fem (male, etc) 2.) Hair I have yet to figure just what the hair pose does? Do you need a special model or special hair for the hair pose to work?
