This looks like a winner.  I tried your code and it works as expected, so
now all I need to do is retrofit it into my scene.

Thanks for the other pointers.  I think I was getting frustrated and made a
few typos in my sample that I don't normally make in my scene files, but I
will double check just in case.

Thanks again!
