Server different map than Client

im trying to set up a server which loads a control panel (WidgetBP) on startup from where i can handle the clients, which are each on their own level.
so what i would like to have, is each client on his own map but controlled by the server (sending events).

im not sure if its even possible to have a different level for the client

this is related to another question where i explained my current approach.

at the moment i think the client loses the connection the server when i open an new level on the client

thanks in advance

You cannot have different levels for the client and the server at the same time.
To achieve what you want you would need to build a master server that dynamicaly launches a dedicated server for each map the users can be in (what most mmos do is have a constant dedicated server for each map and when moving to other maps they simply connect to those servers). The easier way woulrd be having a server with the dedicated servers runing always and move the clients between servers.

Another alternative you might have is streaming the levels you want the players to be in on a single persistent level, so each client would only stream the level they need (being very careful that those levels dont overlap on each other).

All in all it depends on the complexito of your project overall.
