I can't believe all the hubba-hubba over IC7, with still no mention of functional beards. A pity.
This is really the missing piece! Please consider.
A reliable , low overhead, hair and fur generator and editor is a basic need for animals, bearded characters, even grass. Other software has these features. Reallusion needs to catch up. No pressure.
YES! The ability to grow hair would be awesome. Be nice if the hair was mapped out in sections on the scalp, in plots, so you can grow or alter individual sections (eg, top, front, side, back). Then maybe in real time you could comb it and style it. Ooooooooh. That'd be nice.
At least, give some realistic hairs, not only stylish and fun. If not possible, please make / explain the best way to do it with 3rd part program.
