i was playing BeamNG multiseat with a friend recently and we were getting annoyed, because the camera kept zooming out and we couldn't move it for ourselves. He than said that he's getting a laptop just before summer holidays. I thought: "if there was online and split screen multiplayer... than me and him wouldn't have to get annoyed about this.... and we'd be able to call on discord and play BeamNG.drive together, or for when i visit his place or he visits mine we could play splitscreen (vertical and horizontal options for up to 4 players)" I'm decently certain there is a thread like this with the same idea so... sorry if you also made the same thread. later...
Lucky for you, there is BeamMP, a live multiplayer BeamNG experience you can download here: https://beamng-mp.com/ For split-screen, I don't think the developers have added that yet.
i know however this takes long to load and i cant host coz you have to be a patron for the creator its fun tho
