Ah, you seem to be doing that in the level blueprint, I generally tend to avoid the level blueprint and do my coding inside the actual blueprint actors so my previous screenshot is my whole blueprint except for the teleport logic. The way I get the scene capture 2D reference is simply by dragging it over from the components list to the blueprint but it should also appear when you right click and write it’s name.
If you’re only going to have like 2 portals per level it’s fine doing it this way, but ideally you want to have a single blueprint for all the portals and have a way to setup which portal it’s linked to while designing the level.
The part I took from the tutorial was the actual Scene Capture setup (making the render targets and materials and applying them to the sphere) the result of which is this https://streamable.com/x3zwe , after that I just add my blueprint to the portal actors and get the result from my previous comment.
I’m not sure what you were trying to do with the math over there but you were setting the locations of the portals to be relative to the player character which makes them move their position as the player moves, you don’t need to use the SetWorldLocationAndRotation just SetWorldRotation with the rotation being that of the player camera should do the job unless you’re looking for the portals to be looking at specific directions.
