If my world is 30x30 big, and my camera range is say only 20, does that mean that blitz won't draw the last 10 squares of the model, and as you move towards the end, it will draw them.?
AFAIK, Blitz will draw the whole thing because it's one model. Part of it is in view all of the time, so the whole thing gets included in the mix.
If you're really talking about a lot of polygons and it's killing your machine you might think about breaking the model into a few more parts...say, 10x10 cells per mesh. Then you've got nine models. If you're in the middle facing a corner then only a few of those meshes will get drawn.
At least that's the way I understand it. Anybody correct me on that?
