To stream to your console, you'll need to enable Game Mode.
Clicking on "Settings" at the top-right of the screen will present a menu where "Game Mode" can be selected.
The game source layer is where the content you broadcast from your Xbox or PS4/5 will appear when you go live to your Twitch channel after they have been set up to connect to us. This will include any hardware such as webcams or microphones you may be running through the console. If you go live without a game source added to your scene, it can result in a lack of gameplay.
Doing so will automatically add the Game Source to the Project stage and the layer will also appear on the left-hand side of the screen. Clicking on the Game Source layer on the left-hand side of the screen will allow you to hide the Game Source until it is clicked again.
