i suppose their colors match it to a degree, though I wonder why the residents have not evacuated if the sky is on fire and demons are tossing glowing orbs around outside. Maybe that is normal around there.
but burning sky ah ha that reminds me of this old concoction, from may 2000 if the bmp dates can be trusted.
this effect was a nuisance in 2000ish, paint shop pro has some sort of filter that I put over it and I probably needed to have it laid out doubled to get the effect looped, and then I did it 15 more times, which resulted in maybe 3 rough waves, and from there 12 of them could be reassembled into a single smoother wave.
I presume there is something which can automate that now! and of course I had to obsessive-compulsively pre-mirror it even though that makes it inconsistent with regular doom 2.
each frame has two of these; 1 and 3, 2 and 4, 3 and 1, 4 and 2. I can't remember if it actually makes a difference.
this looks like it has a bit of rott sky stuck to it
then I had all black behind the fires so the waving part could be scrolled at .2 speed via hexen-style sky2.
i never finished the level it was for but i used it in plenty of other people's, evidently. I only saw the waving part when glancing up since I simply crammed too much into one sky. it might work better with the lighter row of mountains removed and the flames placed lower.
apparently I screwed something up with my palette at some point since it no longer makes the black transparent in-game, so I just get NOTHING behind the flames, but I am replacing all modified doom resources and low resolution graphics anyway so I suppose that matter is mostly mootly.
