How would I do something like this in UE4?
Only a specific part of the game should render the 3D world, while the other space on the screen should be filled with UI elements (UMG). I want to do this to save performance, since the UI is always hiding certain areas in the game, most importantly a certain percentage at the bottom of the screen.
If I just put UMG widgets on the screen,the world below is still fully rendered, the UMG widgets just hide it after its rendered. I know I could render the game to a RenderTarget and then draw it on my UMG UI, but using a SceneCapture2D as the main camera for the game does not sound like a great idea to me. There is surey a way better way to do this.
