can anyone tell me why when i am trying to make a map the camera window is so dark, you can't see what your building. it's fine a first but you go to save it and then come back to it the camera window is so dark, i added a shitload of lights and nothing happens, when you play the map it's fine only when you go back to build on it this happens? i got 2 buildings 50 feet away from each other, 1 is ok to see and the other black, even with a texture on it and the camera right next to it. plzzzzz help
also when making a map do you build the ground and wall first then the sky and then add buildings and stuff to it? thx to everyone who replys
