Hi folks, did you know that Scupltris can modify V4, V3, body parts via exporting say the head of V4 as an .obj, importing it into Scupltris, make wrinkles, warts, change nose, lips you name it (almost the same as you would do in ZBrush), exporting it back as a .obj, and load it as a morp target.  TG, I think you may be interested.

Best of all folks its a free 3 Megabyte program from Scrupltris.com.  Jan
