for visibility none, am am in void looking for solution. As a project, I have 2 blueprints, first person view mostly took for default UE project and top view with capsule and cine camera. Also I have blueprint for widget so i have some buttons when I pres one it opens one view when I press other it opens other view. Most of this was made by looking tutorials, some things I get it some I have no clue why 
as a widget design its straight forward and easy for design, and connect the dots. It would be cool to have that option in details panel of camera to exclude some objects and don’t see them in viewport, and other camera to see it. That would be best and easiest solution:) I just found some clip and way too complicated blueprint that I can just copy raw with no idea what is happening in background. but its something similar that I am looking for. HERE IS LINK OF VIDEO and here is link of this talk
Only difference is that he really use camera as model 
to me its two cine cameras of UE
