After deletion of HLOD LODActors the initial feature called Generates Clusters wasn’t working. Fixed by creating a HierarchicalLODSetup Blueprint and assigning it through the Project level HLOD Settings. Also created a HLOD Layer asset which may be useful for optimizing navigation.
This only worked when enabling Force Settings in All Maps.
Creating HierarchicalLODSetup Blueprint
Setting up the HLOD BP
Creating HLOD Layer
Setting up HLODSystem through Project Settings
Important: Have to enable Force Settings in All Maps enabled, otherwise Generates Clusters is not working.
Customizing the HLOD Layer
If someone knows why the HLOD window Generates Clusters feature is not working after deleting the LODActors - or why it only works through the Project Settings, let me know.
This approach creates initial clusters, but not for all world actors/meshes - still experimenting with the settings.
