What do I need to do, to set up my GUI overlay in a 3D Scene. I just have a Button and a ColorRect attached to a generic Control Node, but the elements are not showing in my 3D scene.
The FPS Tutorial uses a CanvasLayer to do this. https://docs.godotengine.org/en/3.2/tutorials/3d/fps_tutorial/part_six.html#adding-the-debug-menu
