Multiplayer how to switch between levels

I have an open world game we’re I shan’t to be able to go to different levels/worlds witch works fine in single player but in multiplayer when one player goes to another level all the other players get all there save data cleared. Now if 2 players go to a new level they generate their own level instead of being in the same level. I am trying to do this on listen servers and dedicated servers

a server is hosting ONE map for multiple players. if you want your client to travel to a new map where others can also go, you just need to reconnect the client to the correct server (eg. use the openlevel node or in c clientTravel). You can “fake” multiple maps on a server when using subLevels. remember that you spawn a new pawn in the new level, so save your variables you want to keep in a good (better than pawn) place

Could something like this work on LAN world’s/ listen servers

Sure. You don’t need necessary a dedicated Server. Listen Server is fine, but keep in mind the Listen Server spawns also a Default pawn
