Essentially I'm looking to make the field of view of the camera 360 degrees. I know it's not possible to make the field of view higher than 179 degrees, but how would I accomplish this effect using other methods?
I'm not looking to take a cube map or other equirectangular image and project it onto an inverted sphere, I'm looking to output my current scene in Unity to an Equirectangular 'projection' in the game window, instead of the standard "Perspective" or "Orthographic" projection.
