In open world partitioned level, all foliage seems to be bundled together for loading regardless of size, so if trees are loaded far away from player all other smaller foliage actors are loaded at the same time (grass, bushes, rocks, etc.) Which can make long loads times or hitching.
I have not found a way to seperate how different foliage loads if there is one, does anyone know if it is possible to seperate foliage load distance depending on size or type with different runtime grids?
