How to see the other side from a portal

I have been hitting tabs since yesterday trying to achieve these effects:

But there is no place to suggest how to do it. I have the portal working with a SceneTexture2D and a RenderTarget however I haven't figured out how to be able to pan what is in the other side of the door. Could anyone give me any hints or suggestions?

Thanks in advance :smiley:

I believe this is what you need Unreal Engine 4 Mirror plane - correct reflection and rotation independent - YouTube. , the author also post his sample project in the comment.

Thank you very much! This will be very helpful!. I want to mark your comment as resolved but atm for some reason it’s not letting me, I will try it later :smiley:
