Darklinki Yes, it's kind of this, a layout has more than 1,000 objects it would affect the performance, then we use Save to Object as enemies and life props, each zone by grid, Zone A it would load 20 enemies and some props, in total 50 objects instead of 1,000, if the players enters Zone B from Zone A, it destroys everything have been in Zone A and load objects with "Zone B" tag. It's like occlusion culling, I hope you understand.
