Whats the best way to export a complete level from 3dsmax? Is it even possible to use 3dsmax for level design?

I would say MAX2GS. You can find it in the download section. With it you can export your whole scene. Terrains and blocks all created for you. Even object placement.

Thanks! I will look into it.
