If I can throw my two cents in. What I would suggest is a gui like this: a list box that gives the scene prop actors after selecting an actor then slider then bulges the prop in and out interactively. Move the slider right and it gets bigger, move it left and it gets smaller. In the inner works you simply save off the orignal geometry state of the prop at selection and recompute off the base geometry every time the slider value changes. Set the initial value of the slider in the middle and you can positive and negative bulge prop. Add a "save" or ok button to save off the new prop with a popup to ask what to save it as. If anyone's interested in this I'll see if I can implement this tonight or over the weekend. Bushi- are you using a Mac? I'm getting some extra CR-LF crap on every line of your script when I save it from Netscape.
