Dynamic lights in GZDoom look great, but as soon as fog is introduced into the picture, all of a sudden, dynamic lights look ugly. It's like suddenly the lights are forced to become additive lights. The vibrant contrast will look muddy and washed out.

Is this a bug or are there any technical reasons why this happens? If it's a bug, I'll report and hope it gets fixed one day.

Fog can't be properly composited with the way lights are rendered so it has to be done additive in order to work at all.

I see. So it's a technical limitation then.

Yes.
