Does UE4 support multiple active cameras to render different depth buffers separately?

Unity3D allows you to easily render multiple cameras to the screen, so that you can have separate cameras doing different things (rendering the skybox, rendering the player model, etc).

Does UE4 allow this?

My goal is to have one camera for the 1P player model, and another camera for the world. I want to do this so they can have different horizontal fields of view.

Yes UE4 does allow this. You need to to activate the scripting nodes for this.

What is the scripting node you talk about ? And where do you find it ?
