Multiple Monitor Cave Setup with three Cameras


I have three screens which are aligned as in the sketch below. I have three cameras, each taking up a single screen using the viewport rect. This works fairly well if the cameras aren’t rotated. When they are, objects within the camera’s view are not perceived continuously (the cameras simply seem to replicate the parent camera’s rotation instead of acting as if they were attached to a mount). The cameras should act as if they were only a single camera, meaning that the horizon, for example, should be displayed as a continuous line throughout all three screens. I’ve tried making the left and right cameras children of the main camera, but that didn’t seem to do the trick.

I would be grateful for any help.

Thank you very much!

maybe something like this?

the cameras should always be orthogonal to the screens.
Often this results in asymmetric frustums (well, frusta to be precise)
This means that the orientation of the cameras is imposed by the orientation of the screens,
only the position of the cameras is relevant.
