Hard to believe Quake is 23 with all that fullbright acne all over the place. And while I think some of you mapping folk should really know better by now, even that's not going to help the maps released during the dark age of GLQuake.
From what I can tell, no one else seems to have bothered in all these years, so I decided to step up and comb through 150-ish top maps on Quaddicted to produce fullbright "patches". I'll keep at it, but that seems like a reasonable starting point.
I'm also putting up some tools I've cobbled together to mostly automate the task. So now you can fix things yourself - even if you know nothing about scripts, mapping, modelling or texturing - in about 10 mouse clicks.
