Problem with max size on map

So my map Terra Nova has now grown quite abit since it was last showcased on this forum and i have now ran into a problem, It seems the editor cannot cook maps bigger then 2gb, Has anyone figured out how to overcome this issue ? as its quite limiting on what i can do with my map at this point.

So far i have nearly all resources on submaps except for the landscape it self

Nvm managed to solve the problem by making a seperate Landscape in a sublevel, each umap cant go over 800mb it seems

^ Important information. I’ve just been subleveling/streaming everything onto separate layers. Which means I have to learn the blueprint stuff soon. :frowning:
