Editor very slow or crashes using PCG in huge extensions Unreal Engine 5.3.1

[Gen_X]

I’m using PCG to populate 3.5 kilometers with sea grass and coral reefs, but editor gets very slow or crashes if I scale PCG volume to cover al the areas.

Is there a way to cover all the area succesfuly?
it works OK in small areas.

Solution Unreal Engine 5.41 select PCG component and set generation trigger on “Generate at Runtime”
