How do I add a small second Camera View in the top corner during game play?

Hi Guys,

In my game I want to be able to add a second camera view(perspective) to my screen while playing. Do I use a SCENE CAPTURE 2D component and display the RENDER TARGET in a WIDGET in the viewport?

Isn’t this expensive when rendering the player camera and a scene capture at the same time? This is the way I would do it, but if anyone has a method that is less expensive please let me know.
