Which makes sense when you compare the two renders and notice that the second
one (with the IoR at zero) has a much more crystal-like sceptre.
I don't know how much of an L3P-produced POV file is original POV code and how
much is L3P-generated, so I'll ask this: are either of these lines related to
the reflectivity?
