sector lighting up from gunfire incorrectly?

[denny]

playing doom2 level 6, from start when I turn around and fire pistol or any weapon over the red blood sea, strange lighting effect causes rectangular or triangular brightness on the sea. It seems to be a problem with dynamic lights, because if I turn them off it doesn't happen or if I turn off force additive lights, it doesn't happen. Sorry , no way to up a picture.

Is it similar to this?

I'd test it out but I don't see a blood sea on map06 anywhere.

[denny]

sorry it was map 20. I have three screenshots, but don't know how to up load to this site?

here are the screenshots

with additive lighting on

another with additive lighting on

two more different shots with different slime (not blood) both with additive lights on.

on the last two shots, the artifact didn't occur. Thanks for the responses. I'm kind of new at this.

It doesn't seem to be. The bug in this thread doesn't happen for me.

on your screenshot , gez, is the artifact the shadow under the monster? because that looks normal, but the angular bright artifact to the monster
left side(looking directly at the screen), that looks like my problem.

by the way , I'm using an Asus Radeon 9200SE provided by ati technologies

Ok. Now, where does the fog in MAP20 come from?

The artifacts you are seeing there are something I have seen a long time ago on older ATIs. It's a driver bug that screws up when fogged polygons need to be clipped.

thanks for your time , Graf. Yes , I am using fog settings, gl_fogmode 1, with testfade gray, because I haven't been able to figure out how to change the fog color otherwise. I'm using legacy graphics. the bright, or even dark cause the fog to be way too bright. Can't figure out how to change fog density. The fog effect seems to work on walls fine, but on that red sea, I get the artifact, only when dynamic lights are on and additive lights are on. On other surfaces , even with those two options applied, I get a normal effect.
