Thanks!! (And I like that description--'flaring hydrocarbons'. Great!)

The "halo" above the rising gasoline fire in the center is one of the few
things in the scene that's not 3-D. I didn't want to use media to get that
effect, so I rendered the 3-D gas fire just by itself, against blue (like a
bluescreen), then took that into Photoshop, made high-contrast B&W artwork
of it, blurred that, turned it into an alpha-channel, then re-applied it in
POV-Ray to a thin box, as an image_map.  The box is placed behind
the real gas fire in the scene, and lit only with colored ambient light.
Kind of a cheat, eh? :-)
