Build HLODs infinite loading.

I’ve never been able to load using the Build HLODs option. I tried on 5.5 and 5.6, and I always get an infinite load. I also tried creating a landscape with a single tile, but even then it doesn’t work. I also tried with a blank project.

I’d like to know if there’s a more stable version than these to be able to use these options? (5.4) It doesn’t work either. Or, since these options don’t seem to work for me, are there any tutorials for optimizing an open world without using the world partition and HLODs? This is for a practice project, and for now, I’m stuck on this problem.

I can’t load anything like Build PCG Spline, with the same result.

Thank you and happy creating!
