Landscape Optimazation Tecniques

Thanks, I ment like 2 landscapes where one is using level composition and the other one isn’t. So 2 full landscaps since the play area can always be loaded. I now with some further investegating, i see that i can better just use 1 tiled landscape. But just to clearify. One full tiled landscape and then a other inported landscape with a high resolution. The idea was that the play area has more detail than the background.
