HapZungLam2

I've try looking it up online doesn't seem to have any useful tip on rayswitch in vray

I am making an eye ball.  Everything looks good but the reflection.  I am using dome light with and HDRI for the light and GI.  But I need to switch the reflection of the eye to catch more spec.  Anyone can shine me some tip?
