As the title suggests, my team and I are using Unreal Engine 5 to make a multiplayer game. Our game needs a main server where all the players will join (no 100 player lobbies and other stuff, just one main server). Reading through the docs I saw that in order to use Playfab Unreal GDSK for Multiplayer servers, I need to install the Unreal Engine source version. My question is: Will everyone need to install the source version or is it enough only for one person in order for everyone to use the plugin?
