Ok I want to make a backround for my track thats different than the default one bobs spits out. But when I swap what i want with the damned BKxx files in the sky.mas everything is jumble there seems to be no method to the madness. And after two days of trying and failing i need help. I do have 3d sim ed but that is overly Complicated and has been even more of a pain in the ass than the trial and error with bobs. Please help.
