How do I build correct Landscape HLODs in world partition?

Personnaly, I didn’t have to change the HLOD layer. But if you want to change it, I think you have to change the default by a new one, yes. You can then have an other one for the other objetcs .

What I have done to test it in the default open world scene is :

  1. I Changed the Landscape Max LOD to 5

  2. Delete the previous HLOD by using the menu

  3. I’ve then tested the game to be sure there was no more HLODs (If it’s ok, you should have holes in the distant landscape in runtime)

  4. Then I rebuilt the HLODs with same menu “Build>Build HLODs” as before, but this time I chose Build HLODs.

And It’s working.

I do have the “cross” with no HLODs but it may be a technical neccessity to stitch hlods to the landscape.
