Mirror with scene capture 2d UE5.1 blueprints

Hi guys. I’m trying to figure how to create a mirror using the princible valve used for portal.
I have a 2d scene capture in a blueprint with a circle static mesh in which there is a material that contains the output render texture with flipped UV’s on the x axle.
Now i’m trying to create the realtime system that can calculate the right rotation and location relatively to the player’s camera and the mirror’s static mesh.

Just dropping this here, this is about as far as I got with this: Planar reflections not working - #20 by Cestarian
