Past crystal like in Dishonored2

Sorry for my English.

I need to make effect like past vision crystal from Dishonored 2. What I mean.
I have 2 scenes with one topology, but with differents detailing and textures. For example, house before fire and after fire.
I need to show it in one screen with smooth transformation effect - one part of screen show first scene, other part - show second scene and some border beetween these parts.
Is it possible in UE4? How??

Thank you

this is a clue i guess
