I found the problem. The issue wasn't the HF but rather the normal within
the HF that was causing the strange difference. I read the megapov docs and
found that the normal doesn't behave the same way, so I used the "#version
official 3.1" at the very end of the povray file. Now the HF looks as I
expect it to and the other features (glow lights, etcetera) are there as
well. When all else fails read the docs!
