I want to know how to make clouds pass by around a map. I plan to have a kind of aircraft with a sphere sky box and I want to have clouds pass by either under or half way up the aircraft as if its moving through the skies. Can anyone help me, Colonel Panic gave me the idea to use one of his map's sky box and change texture, although I'm having a problem trying to figure out how to change it exactly.. -_-; every time I try to it messes the whole thing up. anyway what I want to know more right now is to make clouds. :3
