Advanced Lodding - City Building.


I’m trying to build a pretty big city in unreal that’s mostly procedurally generated. I have few defined set of buildings and rules.
Each building has a few LODs already that reduce the draw calls. I’ve precomputed views as and where I can, but I want to gain some extra FPS out of the engine.

I was wondering is there any smart way in the engine if I can have the very lowest lod to be a render impostor. In 4.3 this system was already added so thats great but is there anyway to bind this to the lodding system?
