There are a couple ways to do this . One is to turn them into a sub dividing mat. But what poser are you useing ? P4 or P5 ? Also what model are you talking about ? Mike ? Viky 2 , Viky 3 ....? Also your Tattoo images . What kind of quality and size are they. Are the in a RGB format or 16 - 256 color ? Most of the time when you make a tattoo on a skin it look pretty bad in poser view but renders well .
