Thanks for the reply.

Are you essentially saying "make them 2D transparencies"?  I've considered
that, but I'm not sure how the results would look.  It would be easy enough
for the shadows, but harder for the reflections since I would have to figure
out how to best rotate it.  I might try that.  Perhaps I'm just hoping for
some magical solution...
