I wouldn't consider this an important problem, but it bothers me alot. I had recently bought and installed Medal of Honor: Allied Assault, and it worked fine. On multiplayer, the levels had skies and virtually no fog.
I bought Breakthrough a week later, and it wouldn't install on my computer. Registry Key Invalid, or Product Key. Something. I tried to install MOHAA and Breakthrough on someone elses computer, same CD Keys, and it worked perfectly.
So, I burned my friends MOHAA directory onto a CD and extracted it into my MOHAA directory. I had Breakthrough "installed," pretty much with only a few out-of-game problems. This wasn't in my title of my problem, but it's something that happened.
Anyways, I noticed that in Breakthrough, I have no sky in my game, and the fog is thick on every level, including the original MOHAA multiplayer levels that never had fog, EVER. Black fog will give me a black sky, even when the sun is out and blinding me when I look up. Is there a setting that will give me a sky, or lessen/remove fog?
