I am making a zombie game and the game will need to have a lot of zombies in the world like dead rising 3 but when i put a 100 of my zombies into the level my game starts to lag. So how would i be able to spawn in thousands of them without lag?
It’s quite non-trivial - I don’t know if Epic solved this problem in Unreal Engine, but in Unity it’s impossible to make a crowd in easy way. The Hitman series are known for fact that last titles were able to have insane amounts of actors ( here ).
There is also a discussion here. Maybe it will help.
