Integrated Twitch Chat
If you have signed in to your Twitch account, you will see a Twitch icon in the overlay. When you click on this icon, a window will open. This window is XSplit Gamecaster’s integrated chat system. From this window you set the title of your Twitch Broadcast and participate in your Channel’s chat. You can also use text commands to moderate your Channel.
The control symbol represents the ingame hud visibility and activating it allows you to see your Twitch chat within your gameplay. You can use the opacity option to create a background for your chat to make it easier to read.
One of the most exciting new features for XSplit Gamecaster is the annotation mode, which lets you draw directly on your gameplay. You can activate annotation mode by pressing the pencil button in the overlay. From there you will be given a menu which shows you the different options available in annotation mode. Press ESC to exit annotation mode.
