How can I define a non-circular stop in Sequential Mode?  For instance, I would like to define my stop surface to be a rectangle.  When I apply a rectangular aperture to a surface and then check the box to make that surface the stop, it still creates a circular exit pupil.  I use the Float by Stop Size setting for the Aperture Type.

Applying an aperture on the stop surface should change the shape of the exit pupil.  I did a quick check using a paraxial lens with a rectangular aperture and everything seems okay:

 

How are you determining the shape of the exit pupil?
