Hello, I imported a Metahumain and followed some steps by deleting some LOD in order to prevent the haris disapearing from a certain distance, but as soon as saved and reopened this, I got an error from these LODs, making Unreal crash with my project :frowning:

Assertion failed: StrandsLODCount <= LODScreenSizes.Num() 
[File:D:\build\++UE5\Sync\Engine\Plugins\Runtime\HairStrands\Source\HairStrandsCore\Private\GroomComponent.cpp] [Line: 2700]

Dont delete the LOD. Just make the min LOD level 1 or 2 or whatever you want the minimum LOD to be. No need to delete anything.

Do you have any idea how can I recover the project now that I deleted these and that I can’t load the project ?

This is why you need backups.
But if you know exactly which metahumans LOD you deleted then you can try deleting the metahuman’s folder. You can get them back from quixel.

Before you delete MAKE A BACKUP, this might fail or not do anything.

This was exactly my issue, I didn’t need a lower LOD so I deleted it. Got the same message on start up. The fix was to go into my project files and delete that meta human and re-add them into the project. Thanks @Riipitud1 !
