had the same problem yesterday with the total hair.the way Ken wrote is the normal way and its working good.but seems to be not on all hair.my way : in the pictureeditor:load your hair in the first box, load your transmap in the second box , do not select "blend transparency" . in the matlab select the first button " diffuse color" and the button for transparence at the bottom and play a little bit with the transparence slider. posted a pic with that hair in the posergallerie yesterday title "???"
