Hi,
Spawning a player is done per machine/device. When do that, photon will also spawn a remote instance of that player on other machines connected to the same room.
so bascially, when you join a room, you instantiate a photon prefab, and that's you in the game. then any device you run and join that same room, you will end up seeing each others in that room 3d world.
Bye,
Jean
