Well I'm not sure what was doing it, but I changed skys again, using a different choice from the sci fi skys, and now there is no graphic hole in the sky. I'm going to have a look at these x sky models in another viewing program. The engine works, its something with that sky model. I wasn't using the default. Another of the buiit in choices. The substituted sky looks beautiful, and yes I'm aware its not designed to do outdoor levels. But let me tell you my first exposure to virtual reality. It was a demo, fifteen years ago, that came with a simple 3d world engine with much less resolution. I can't rememebr the name of it but in the demo you moved through 3d rooms. Finally at some point I moved out of the rooms onto the roof with a railing around it, all reprsented in low res of course. And when I got out of the hallway and suddenly blue was above me, suddenly the world felt infinite, it felt real. So I like to enclose a little courtyard with the sky above. Makes the player feel they're in a real world when they think they can go outside. Have to enclose it tightly of course, surround it by walls or the engine moves too slow. But its great when you feel that infinite sky above you. Its a psychological thing. And thats what we're creating, the sense of reality, like when we put decals of explosions at the muzzles of weapons. Making it believable. Glad to have my sky back.
