Hi. The : is a command delimiter. So you can write multiple commands on one line if you want.
I'd use 1 meter per Blitz Unit. Yes, you'll get some Z-Buffer inaccuracy if you're far away from the center of the scene. I think it starts somewhere at 32000 untits away from the center (or even earlier?). So one meter per unit would still work for big levels. You definitively cannot simulate an airplane that flies around a planet that has a radius of 12 million blitz units (like terra) unless you move the landscape towards the airplane frequently, so the airplane remeins inside a certain field near the center.
