Impressive!  I think the lighting and tonal qualities are *just right*--the way
our eyes would adjust to such a scene. The smoke is wonderfully backlit. A nice
design overall.

Yeah, there *is* a 3.6.1 problem with radiosity and media-in-an-object; the
media generates radiosity lighting on objects *outside* the box, but not inside
it. I can't really tell if that's your snow problem, though. Your box appears to
be intersecting the mountain, so there's bound to be a different look in that
area, just from the radiosity gaffe.

Here's a goofball idea for a workaround: Make a duplicate of the mountain HF,
translate it slightly upward, and difference-it from the box. That will create
a thin 'no-media' zone between box and visible HF, which should correct any rad
problems there.
