How to create new viewport in current camera?

I wanna to create a 2d wire frame mini map of current 3D level that rendered in left down of the current screen. How to do it through blueprint?
Would i make an ui widget and connect it to a camera component?

You can achieve it in several ways. You might use what is called “RenderToTextureTools”

Or you can just make it with UMG, and RenderTarget asset. If you really interested in a step by step tutorial for this method, you can check this Wiki post.
