i tested this now and it works. not physical realistic but could be used for faster rendering.
the process is the same. you first position what you want to be reflected n the eyes. then you load BB's GenIBL  and render it out. then in HDRshopt you make a reflection image.

you need only Poser,GenIBL and HDRshop. everthing is free. and it takes 10 - 20 minutes.

i see noone giving an opinion. is it not good?
