The 2D Scene Capture is more like a monitor as you’ve suggested. It’s a way to get a clean image back but it adjust the view based on the players position.
Sorry, did you mean “it DOES NOT adjust”?
In this case, would it be possible to adjust it via a blueprint?
Checked the documentation, didn’t find a way to really get a clean reflection.
By the way, the “mess” you see at the intersection of the two mirror (which if rendered in a cleaner way would also be the coolest part, where the mirrors mirror each other) is just due to screen space reflections. Tried to improve them tweaking the parameters and the screen space reflection quality but without good results…
