It solved the problem to me. Finally, i could build a 4.033 x 4.033 Landscape after type this command that you told (landscape.Nanite.MarchingSquaresVisibility 0), using UE 5.3.2. Thank you, man!
Unfortunatelly that did not work for me ((( UE5.3.2 keeps crashing

Yup sounds good!!
Nope its not. I get this in my project, 5101x5101, very large detaied scuilpting and meshes,nanite, lumen. Its a ram issue pretty sure. A basic level,is tiny enough to avoid ram issue no doubt.I need more ram,sadly to avoid this .Shame this isn’t coded better.
If you’re using a World Partition level you can load smaller sections of the landscape and build Nanite for them piecemeal instead of building Nanite for the entire landscape all at once.
I love you this has been bugging me for a month 
Im having this issue again with a very large landscape broken up in 4 tiles.
landscape.Nanite.MarchingSquaresVisibility 0 doesnt exist in 5.7…. so thats no help unfortunately.
Sadly, ain’t perfect. I got around this by 1) disabling Nanite till sculpting is finished, and 2) splitting the Landscape into smaller landscape sub-levels (level streaming) and saving incrementally, then re-enabling Nanite. My computer managed to save in parts like this, hope this helps
Soooo, I actually found a fix for this which is this command.
landscape.Nanite.MultithreadBuild
I’ve a 12 core 24 thread CPU so I though this may help me and it did help. No crash and the landscape has been built now.
Unreal version 5.7.4 btw.
Edit1:
I can’t complete the Save process after that tho, So my landscape in Nanite ready now but everytime I try to save my project it stucks at 69% and stays that way for more than an hour now.
Any ideas?
Still doesn’t work for me anything map size beyond 16x16 crashes, here the numbers i got it to work for me:
Section Size: 255
Sections Per Component: 2x2
Number of Components: 32 x 32
Scale X: 100
Scale Y: 100
Scale Z: 100
After creating the landscape:
Enable Nanite: On
Build Menu: Build Nanite Only
World Partition: Enabled
Cell Size: 12800
Loading Range: 2 to 4
Project Settings Rendering:
Nanite: On
Virtual Shadow Maps: On
Hardware Ray Tracing: Off
Just have to wait for epic to find a better way to make Nanite map conversion without crashes.
