Hey guys, in the past view weeks I made a UE4 plugin called TwitchAuth (Twitch Auth in Code Plugins - UE Marketplace) to authenticate Twitch subscribers in-game. My use case will be subscriber builds, to have the link public but only subscribers can authenticated in-game and play it. I don’t know if anybody of you is interested in stuff like this, but I wanted to put it out there anyway!
BTW, plugin is completely open source => GitHub - mrbandler/TwitchAuth: Unreal Engine 4 Plugin for In-Game Twitch Authentication.
