So I'm using Unreal Engine 4, I'm having trouble getting started with PlayFab and Thunderhead. I have no idea how to do this. The documentation mentions a "Game Server SDK" but I'm not sure if I need that for UE4 or whether the UE4 plugin built with a dedicated server in a UE4 source build is enough....I also can't seem to find examples for UE4 anywhere. Can someone at least help me get started?
