crop and scale up USceneCaptureComponent2D

Hi all, I’m working to recreate a portal effect using this video as a reference:How were the portals in Portal created? | Bitwise - YouTube
I’m stuck at 4:08 in the video where you should crop the camera’s view and then scale that up to the resolution. Does anyone have any idea of how I can implement this as I’m using a USceneCaptureComponent.
Any help is much appreciated, thank you :slight_smile:
