Perspective Camera on only one axis.

Hi everyone,
I’m creating a 2D game with a parallax background. I am using a perspective camera to do this. I’m looking for an effect where ONLY the X-axis is effected by the perspective camera, and the Y-Axis is not.

I know this can be done with an orthographic camera and scripts that manually move the objects, but it just makes things simpler to use a perspective camera. Anyways, is there a way to make a perspective camera perspective on the X-Axis and orthographic on the Y-Axis?

Thanks for the help!

Thanks for the help guys. I appreciate it!
