Hey realDunkin,

right click on your HLOD file in the content browser and do a validation on assets, what problems you got ?

if you validate assets and dependencies, you’ll get more results, but some fortnite props will throw errors up, but these props can’t be modified to address the errors, you can usually ignore them though because they will still let you build HLODs and launch.

I often accidentally attach spatially loaded actors to non spatially loaded actors or vice versa, which always causes issues.
another could be an invalid texture, I had problems with a material made from a modified Fortnite CR_Damage Overlay instance.

Wow, thats full on…

The entire lot references nothing inside your projects folder…unless I missed it, maybe do a search for your project name just in case.

Have you done any custom stuff, or changed spatial loading on spline stuff.

What you may be able to do is remove things from being in HLOD, start with all small things and everything that won’t be seen or doesn’t matter from a distance.
Delete the HLOD before you Build HLOD

If they still fail to build, stash all your HLOD enabled stuff in a seperate folder, and turn off HLOD on large amounts of them and test to which ones wont build.

Any offensive ones can be taken out of HLOD and have them not spatially loaded if your memory limit allows.
