Thanks for the replies guys.
The neo.pk3 map linked isn't loading in my game for some reason

. It keeps returning to the main menu.
If it takes 5 minutes to create such a map with couches etc., I'm hoping that it'll take you less than 2 to create what I need. I don't need anything in the map at all. I referred to Matrix just to highlight the "empty" nature and forgot about TV and couches being in there (tight observation). I just need a big empty map, preferably white, that's all

. I'm hoping you'll help me on this one.
Rookie One.pl, thanks for your suggestion too. But I don't even know the basics of MOHRadiant and as such, I end up with lots of compiling errors which have very little to do with caulky sky textures or white farplanes
