Hi LeFxGuy,
I was able to reproduce the issue you’ve described in 4.13 and 4.14 without any problem but in my latest internal build of 4.15 this doesn’t appear to be an issue that I can. The HLODs when Disabled via the World Settings the Generated Clusters are disabled as well.
Look for this to be addressed in 4.15. If the issue is still persisting at that time please feel free to reopen this ticket here.
Thank you!
Tim
