I have a scene (lest assume, large glass table I want to looking through) and I want to render with 4 displays (each 1920x1080). How can I set up camera for this, I want the "glass cube" to fill entire scene (all four displays).
If I use single perspective camera and I want to see entire scene, I got stretched image near sides - in other words only middle is correct and sides are stretch. If I correct this, than my scene is not filling entire window and is small.
I have tried to create single camera for each "display", but this will cause frustums overlapping and I have part of the image rendered twice (logically). I can use orthographic-camera, there is no overlap, but I have no perspective.
How to solve this problem?
Edit: I am using Unity 5
