Building HLODs taking forever.

Hi,

Not sure what is going here but building my HLODs used to only take about 60 seconds now I sat for over 30 mins and they still won’t build. I tried going in and duplicating my level and building that, same issue. It started happening after I did a really long light bake with the Volumetric Lightmap Detail Size set to 50 from 200. I went back and put all those settings to the originals and It’s still happening.

[Screenshot of a build. This has only been going for 8 mins but other went on for 30 mins plus before I cancelled them. This used to take 60 seconds]

UPDATE:

Even the Minimap Generation is taking ages.

UPDATE:

I found a solution on reddit from a guy. Running this command in CMD builds the HLODs in under 60 seconds.

Here’s a tip for anyone who struggles to build HLODS and needs to wait an hour. : r/UnrealEngine5

This doesn’t explain why they started taking forever to build through.

It supposedly takes some time to “build and compile shaders,” but only the first time…

Yeah this happens every time. And it only started happening. Before it took 60 seconds to build. And if I build with the console commands it only takes 60 seconds.
