The docs say that terrains will mess up under orthographic projection, which kind of suggests that other entities won't -- am I right to expect this?
I find it hard to believe that cameramode 2 should chaff up *every* entity - although I know it does cos I tried it myself.Didn't use it in the end cos I couldn't be bothered to figure it all out. And it made my skybox look weird. :)
I seem to recall that enabling the w-buffer made some difference, so you could try that. Haven't got Blitz on this PC so can't check it out for myself atm.
