i downloaded some zip file titled "gilbert"i think it was under maps and mods, well i got it off this sight. anyway the description said, lightning sky bloody toilets and so on...my problem was that evertime i played crossroads or destroyed city the sky looked nice however it screwed the trees up and shaded everythig in the distance grey, i deleated the file and now everything is fine. i running a gforce2 chip. just wonder if anyone had the same problem......
