I'm going to upload the script to the Renderosity Freestuff as soon as I'm happy with it - I'm not sure how long to wait to see if anybody comments on the script itself.  I've already fixed a couple of bugs, but one I'm not sure how to handle - the line...

mats = act.Materials()

...(around the 22nd code line in the first post) errors if you have, say, just a camera in the scene as the selected actor. I could use an

if not act.IsCamera():

but I wonder what other actors will cause similar problems?
