HLOD...totally incomprehensible, it keeps not working, crashing... I'm so bored

Hello guys,

I am working on a game which is almost finished… Well, that’s what I thought…

Indeed, there a some levels which are pretty complex and where FPS are pretty low sometimes (~10 FPS). So I tried to use HLOD (with different settings like those in the picture 1) but for some f***ing reason, after 2 hours of building LOD it crash, saying “Out of memory blabla…” or it opens Crash report window (at around 40%).

The problem is I have a good PC so this is probably not the reason. Indeed I have:

  • Ryzen 7 1700 (8 cores/16 threads)
  • GTX 1060 6GB
  • 16GB RAM

I tried to check Simplify mesh, tried to uncheck
I tried several values on Cluster generation settings

NOTHING work…

Is there somewhere a file which can tell me what is causing this problem ?
Maybe I am not doing it the right way ?
Maybe this is not how to use Simplygon ?
Is there a PRECISE tutorial on how to do ?

PLEASE HELP :’(
