I don't know man i hope broken switches get fixed soon.
Lightmapscale on models is 0.125. Shadows are very dark now, but to be honest i like it. I always liked strong shadows and high contrast. Makes the game look like Doom 3 a little.
Thanks Flajeen. Maybe I'm just being picky and wasting time trying to fix something that either doesn't needs fixing or can't be fixed.
