in all honesty i havent found ANY eye kits for poser that are any good in my opinion,the only ones that are any good are from characters that ive bought and luckily some have been good. i dont think its the iris that seems to be the problem,more how the material is setup for the whites of the eye, but i dont do many renders in poser i tend to use cinema 4d to alter the materials further.
