I have made a nice looking sky box (in my opinon). put in the zone and set the fake backdrop on my main suptraction brush. the problem is when I play the leavel in practice mode the fakebackdrop image smears and echos. I have changed the size of the the brush and that doesnt seem to make a dif. The sky box is 256x256x256 so that the skyline tex fits is perfectly. and the fake backdrop brush is about 800x2000x2000. Any help would be grately apreciated.
