Loading times with large world

more info in posts

I am working on a open world game, i have one 16km by 16km landscape that is split into 8x8km tiles, but stiched and world composition removed, as i want my game to be open world multiplayer

with just my map ect the load times is fast, but once i add procedural foliage the load times become forever…

i have a decent computer and will post specs at the bottom, this i without collision enabled, if i enable collision on only LOD0 and disable it on all other LOD’s (i think im doing that right?) then it becomes MUCH longer

right now on my system my world takes around 30 minutes to open in UE, with collision it takes 1+ hour…

and i just want to add it stalls on “initializing world”
