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.
