Multi Viewports on Multi Monitor display

I’m using a 3 monitor setup. One straight in the middle, and another monitor at an angle on either side.

I want to run my level with 3 cameras (+/- 60 degrees from center, 60 degree FOV each) in order to show a 180 FOV if you’re sitting right in the middle of the 3 screens.

I have my first person character and I’ve added 2 more cameras as children to the main middle camera so that they all rotate together when I move the FP character.

How do I split the screen view so that I have 3 strips on the screen that each show the view from one of the cameras when I play the level?

Is this to be done for a game? The workflow would be different based on the needs of the project. The easiest solution is to get 3 different viewports and assign each a camera.

It is for a demo I’m working on that controls the camera movement with an external sensor via arduino. So not really a game. Just a demo. I have 3 vertical monitors and just need each of them to display the view from a different camera so that the FOV feels correct when you sit in front of all three of the monitors and turn your head to look around.
