Known my me? ...... umm dunno ... a while. I don't think it was really "discovered" because its just a matter of reading how the BODY scaling is achieved. If you look over some of the old Poser 2 CR2's you can pick up valuable tips. But I'm still learning. For example it was only the other day that I discovered that you can create a PZ3 file that auto loads a Python script on opening. So there is always something new to learn.
