Malcolm iris and pupil not rendering in one eye

[Nostrockin]

Hey, first off thanks so much for this rig. It's pretty amazing. I only wish I knew how to model better so that I could modify it further, as I'm using it in everything.

Second part! I'm having a problem with a scene where his left eye isn't rendering the pupil or iris texture. I'm not sure why it's only happening to one, or why it's only happening on the 2nd smoothing level... I've attached a picture. Anyone encountered this before?

Thanks very much for any help
