Update: rebuild HLOD build HLODs only for imported static meshes

Also having HLOD issues after 38.00. After rebuilding HLODs for my map, only some are generating properly while others with identical World Partition and HLOD settings are not.

  • Buildings and props: Partial HLOD generation (some working, most not)
  • Trees and foliage: No HLODs generating at all

Top image is HLODs showing up in-game after rebuild. Bottom image is the editor view.

We’ll have someone take a look.

I can confirm this issue as well in a map where I rebuilt HLODs after update to v38.00. HLODs for many actors are now missing in a game. The first hint that something is not OK was a value of Memory Calculation that was 3% lower than the last time before update to v38.00 while I didn’t make changes that would justify a decrease like that (but with updates of UEFN we never know if something changed in the calculation overall, so it is just a hint).

Thank you!
I also noticed that the world partition system has been modified. Before v38.00, in addition to the Default HLOD Layer field, there was an additional HLOD field in the runtime partitions property. After v38, this additional field was removed, and now there is a new HLOD partitions property where you can set the cell size and loading range of the HLOD (I tried to set it and rebuild HLODs, but HLODs still don’t appear)

There are several “neverbake” fortnite assets missing from 38.00… things like haybale, barrels, showerhead, etc… so I can’t even build HLODs at all with these Fortnite assets on map. Here’s but a small example seet:

LoadErrors: Warning: While trying to load package /Game/Building/ActorBlueprints/Prop/Gym_Showerhead_02, a dependent package /Game/NeverCook/EditorUtilities/Environment/ActorSwapUtility/EUC_ArtRefresh was not available. Additional explanatory information follows:

The uncooked file would be expected on disk at ‘C:/Program Files/Epic Games/Fortnite/FortniteGame/Content/NeverCook/EditorUtilities/Environment/ActorSwapUtility/EUC_ArtRefresh’. Perhaps it has been deleted or was not synced?

If I’m not mistaken, these errors have been present for some time. With this patch, no (or very few) assets are built.

Can confirm this is happening to us too.

I’m also seeing HLOD issues after 38.00. Rebuilding HLODs doesn’t fix it.

FORT-1006684’s status has changed to ‘Ready for QA’. A member of the QA department is investigating the issue.

Have anyone rebuilt HLODS today after the update?

Having the same problem here. Please advise.

still broken, but the issue is in ‘Ready for QA‘, so they should fix it soon
