Spawning object in MP game

[knack]

hello.

I learning multiplayer and have doubt about the better approach for spawning objects in the level/map.

ATM server spawn the objects (random) on multicast event, that work fine, my doubt its when someone login after that spawn event occur he can’t see the objects spawned, how i managed this? i think i can work/get the idea with only some theory, but if anyone knows some sample project… better.

I must keep track of object+transform spawned and spawn on client side when new login?

thanks.

I search without luck info about that topic, but i found that on Unity

Once in the spawning system, state updates are sent to clients when the object changes on the server, and the object will be destroyed on clients when it is destroyed on the server. Spawned objects are also added to the set of networked objects that the server is managing, so that if another client joins the game later, the objects will also be spawned on that client.

That not exist in UE4 right? i must do that no?
