multiple cameras on the one screen

I just played heavy rain, I know I’m a bit late. Awesome Game, but one paticular effect struck me as something I could use in a game I’m making. Here is some Gameplay with camera effect I’m trying to get. It starts at arround 17 seconds, where there are multiple cameras on one screen, and It is split up like that. How can I do that? And Is there any way to have one camera be from a different scene?

I don’t think you need differents scenes but just 3 cameras in only one scene to do that.
And this topic can be a good start :

and in the camera documentation, there is the normalized viewport value which can help you to do what you want :
