the pupil is a separate piece of geomerty...i can change it so it's not affected by the lattice, but then it doesnt follow the contours of the eye...the pupil stands off of the eye and it doesnt look right. So i want the pupil geometry to follow the curve of the deformed eye (i.e. bend to match the shape) but i dont want the pupil to actuall stretch and squash as it is now
