So I am wanting to make a tv app that is basically nothing more than an overlay that has chat coming up the side. I know that samsung supports overlays, but I do not know how to accomplish it in unity. Is there a way to do this? My hole app is literally a facebook login, and then a clear overlay that shows push notifications from the cloud up the side. I know how to do all of this in unity besides it being an overlay. Any help on this is greatly appreciated!
