It did spawn a prop in the scene, but I cannot find any new Koshini.obj in my Poser5 entire folder. Besides, I imported the original Koshini.obj (towards which all my Koshini characters are pointing) and it had no problem. I read the script. I don't understand clearly what it's meant to do, but I can see it chose the left thigh and moved vertex number 13 along it's normal (which was mostly Z oriented, hence the aspect). Now is there some sort of "clipboard" where Poser stored the modified koshini.obj, and to which the next koshini characters I loaded where redirected ? (something like the list of texture maps that stay into poser's memory even if you delete them from all materials) BTW : I decided to delve a little into Python (in the hope that I could make myself a new GUI...). I remember you (Ockham)said that Poser5 SR3 had changed the way that Poser implemented Python. Does this make a change in Poser's classes and methods (as defined in the original documentation), or have any impact on the syntax ? And does PoserPython include all the Tkinter libraries ? Thanks again.
