try ITransform and scale th center (it will morph through a matte so you
can control the morph's falloff with a simple blur

Hi, I'm working with footage of an eye and I'm trying to dilate the
pupil ever so slightly. The challenge for me is getting the iris to
look as it is contracting accordingly. By rendering out a normal
shader from Maya (one channel from top to bottom, one from right to
left and one with facing ratio) and using it with an IDistort (same
method as this guy fakes refraction in Nuke:
https://vimeo.com/30058027), I've managed to push the pixels around
the pupil. It works to some extent, but doesn't seem like a good way
of achieving this.
How would everyone else go around doing this? Preferably in nuke only.
