Most UE4 tutorials on creating a mini-map use a Scene Capture 2D in Realtime, which does the job, but :
You'll face a significant and unnecessary performance loss.
This way of using Scene Capture 2D consumes a lot of performance. I recommend looking up more information on the internet or testing it in the engine and monitoring the performance
It's going to be challenging to edit only what you see in the mini-map without affecting the level.
But by using the Orthographic projection mode on a camera (a great feature that's there by default thanks to UE4), you can just take a single high-resolution screenshot and use that for the map system without sacrificing half of your frame rate with wrong methods. Also, you'll be able to edit your screenshot in your photo editing software to make it look cooler like a stylized map
