After converting my 5.2 project to and 5.3 and on converting my landscape (13x6km 1m resolution, about 80 Million vertices) to Nanite, the operation eats up my full 192 GB Ram then crashes. Scene is World partition, so landscape is in about 350 Streaming chunks. So UE should convert them one by one without problems right?
Anyone converted their big landscape to nanite with 5.3?
64GB + 100GB of virtual memory wasnât enough to get an 8k landscape converted, just processes for 20 min and then crashes. At this point there must be a memory leak or something, because how an operation like this can suck up so much resources I have no idea. I guess unless they expect all developers to have a terabyte of memory laying around or something.
Same here, I was trying to convert a bunch of landscape proxies at a time, to see if that works, instead of converting the whole landscape (which should also work). 44 proxies were done in a few seconds. But then when I go to save it, UE eats up ALL the RAM and crashes. Canât save a Nanite Landscape it would seem. This is broken. My landscape is 8x8 km.

This wasnât an issue in pre-release 5.3 ⌠what have they done!?!
Same problem here with an 8k landscape.
Tried building a few landscape streaming proxies at a time and then save. Eats up 100% memory then crashes.
A 4k landscape imported with no problem and RAM usage peaked at 50GB.

I recently have samiliar issue, 13900k + 4090 seems to be a bad combination some how. But I kinda found a work around, goto th Intel website and download âExtreme Tuning Ulitilyâ, then set p-core and e-core down a little bit, and the crashes and blue screens never showed again. Just give it a try.
I see a lot of people reporting problems like this, all related to 4090+13900k. I m guessing the hardware development is too fast for the dev team to experiment every combination.
Sadly I have a AMD 7950x3d and not an Intel. It isnât Intel related.
Same issue with 248 chunks: more than 100GB of ram in use and crash.
My solution: select a few chunks, rebuild nanite, save, repeatâŚ
Confirmed on W11 Pro 23H2, Ryzen 5900X, 204GB free memory available for the editor, 24GB VRAM also sometimes runs out while working with landscape.
