I am trying to run a three gaming/ streaming pc setup with the Elgado 4k pro mk2 in all computers including the one that is streaming. The computers are connected via LAN. However, i am unable to see the capture cards from my streaming computer that's in another room on OBS. I intend to run multiple cards on one stream for a variety of scene selections. how do I connect all of the game play over LAN for streaming, what am I missing?
