With “So set up multiplayer, make player controller send exactly same input to all pawns (that control cameras).” you mean, that I’ll take the first player (pawn) and attach all the other players (pawns) to him? I just tried this and if I move the first player (master) in the editor all of it’s slaves, the attached players. move accordingly, which is what I want.
I still have to figure out how to assign the the monitor id to the camera. Ok, I added Event Begin Play within the BP editor. I don’t see how to assign a monitor ID.
