Looking at your file made me notice something that tells me definitely that you
and David are correct. I never noticed before that there is a filter value in
there after the rgb vector. Naturally that would skew things a bit.
So David was right with his theory and you are correct as well. I looked back at
my POV file and commented out the filter stuff that L3P/MLCAD inserted (why
would they do that, anyway??). Here is the (correct) result:

It doesn’t have the orange shadows, and I’m not sure why, but the flames are the
proper color anyway. I just had an idea for a flame color that would look really
neat (and pretty realistic) but that’s neither here nor there. At any rate, you
were right and I was wrong. :) I totally missed that filter stuff...duh...
So can I begin a campaign to remove filter values from L3P-generated POV code to
instead work with just RGBT? :)
