I'd like to use cinemachine on my next project. It will be a side scroller with 3D level geometry. The problem is that when using a Virtual Camera that is set to perspective you can't use a Cinemachine Confiner that is set to Confine 2D mode. Is there a way to use 2D confinement with a perspective camera that I'm not seeing? If not, is there a more intuitive way of setting this up outside of creating box colliders for you vcams and messing with the z size and the camera offset?
