I like very much the idea of face filter. There is lot of potential and I see the integration with crazy talk and Iclone. What about HDRI and high resolution skins? Face filter could even be an alternative for photoshop in face texture editing.
But I don't get any update since very much time. Please don't forget this wonderful tool!

I would like to know this as well . Does it have a place in teh PBR pipeline , ?  whats the best way to use it now .
