So like in the title. I have a fairly large landscape (aprox. 1000km2). I used landmass plugin to shape it and it’s working alright. I saved it and all that fun stuff. When i want to enable nanite on it - it allows me to do it. I cant save after that tho, nor build or rebuild.
Below i am pasting an error that i get when trying to save after enabling nanite for the landscape:

I see that it says OUT OF MEMORY but i never get higher than 40gb of ram usage.
And the Video Memory stays stable on 7.1/8gb.
