Hey all!Could anyone tell me the basics for creating a UI for a 3D game?I just don't know where to start to set it up.In Blender I used to have 2 scenes, one for the game, and one scene for the UI, which I added as an overlay scene on top of the game's scene.After that, I had to communicate between these two layers.So, how is UI done in Godot?Awaiting all the ideas.
