Hi Mosel3y!
Well i simply add a planar reflection in the scene, i tried as well to make a blueprint with the planar reflection in it, but i don’t figured out how to make it work (I’m a artist not a programmer) 
If i simply add a planar reflection component in the scene in the detail i didn’t see array called ‘‘Hidden Actor’’ like you said. I must do something wrong.
I was thinking this should do the trick doing it in the Level Blueprints direcly, but clearly… i’m doing wrong lol
