Perspective Based Invisible Wall

Hello beautiful ppl,
I was wondering how, if it’s possible, I could implement an effect like this in UE:

The wall has geometry modeled on it but is completely invisible from outside of the room.
For my game I want the entire wall to be culled when looking at the player in an exterior when in 3rd person. I have tried using back face culling but geometry sticks out visibly and ruins the effect.
All help is greatly appreciated!
Thank you
