As the title says, is it possible to have two application windows running one game instance? With one of them having a set of controls, and the other being a separate camera that shows the scene.
Surely it’s not impossible. Look for UE4MultiWindow at github. I just tried it several weeks ago, it’s a toolbar button in the editor, which opens a window using SceneCapture2D in the scene. Although it might take efforts for you to make it look like the video.
I made it work using nDisplay and using the Two-Monitor Preset that comes with the Starter Content. I then disabled the viewport on one of the nDisplay Nodes, as I only needed that screen for the UMG Widgets. It works!
