Mask complete Scene - Double Exposure Effect

Hi,

I would like to achieve a double exposure effect in Unreal.
I know I can mask a material, and with a flipbook, I could even make the Mask animated. But is there something like this for the whole scene?
Like in that music video (Taylor Swift - Style - YouTube). A few times they use double exposure for compositing smoke inside the singer’s body and stuff like that.

Thanks in advance!

I’d like to know too, have you had any luck with this?

What I can offer is: Double Exposure in Unity - Unity Tips - YouTube

And there’s also plenty of talk about this in the Unity forums, let me know if it helps.

Lastly, please don’t make me watch a TaylorSwift video ever again. Now I actually know who she is. That’s 5 minutes I’ll never get back.
