Hi, @Pitbulllx When I tried to use the “build all” feature the first time it crashed on the city scene, the second time it started crunching and it has been going on for over an hour now. If have haven’t can you try building it again ? ---

I’m running UE 5.0.1 and working on the Matrix City project Large and Small levels. I have a 6core 8700k and 32GB of RAM, with M2 drives for storage. I was unable to build HLODS for the Big City Level without adding an additional 200GB of page file storage. Then it would take 10 days on my system to build… But it would build and will rebuild the mini map. The small map on the same specs would take 20 hours to rebuild HLODS. Typically when I see 0x000000x errors, its been a memory leak or a memory run out (fill up.) So try a large large page file, if you are working on the city project. I am trying to find out how to rebuild clusters and not the whole hlod, hoping that is possible, as … 10 days of compiles to see updates past 1 block in game is impossible. When watching details about how Epic compiled the HLODs for the City Project, they mentioned it took a day on a network of “20 systems” - This is equal to about my 10 days on a single 6 core 8700k. So the HLODS are beyond solo dev compilation at this time… for City Project type Large Levels. ---

Im using 5.3 had the same issue. When pressing stop build it would show me error to the trigger boxes refferenced in the level blueprint. The issue was tha the trigger volumes where included in the HLOD for the world partition while in the same time called in the level blueprint. All I did was make sure those actors and theyre components where not included in the HLODs and that fixed it for me hope this helps.
