Hello all,
I had an map and i added an map sky: newvillers but before that i looked at the other skies... so i choosed and then i put in the settings. i started the game after compile and it says that there cannot be two skies. i looked at the radiant where the second by mistake sky is but i could find it... how to find it?

few ways of fixing it

open the map in notepad and look for the texture you want to get rid of - it'll have a brush and coordinates assigned to it and you can just delete those lines of code

it's probably more reliable to delete the new sky you made to see if any of the old sky remains. If you can't find the old sky, try texture find/replace and replace it with nodraw_notsolid, or whatever equivalent cod2 uses
