Iray Glass shader transparency problem

tsiga001

Hello everybody!

i'm newby, and have a little problem with the built-in iray glass shaders

I tried out a lot of presets, the last is a Solid clear glass shader, and don't understand why are the lenses white...

what i doing wrong?

thanks so much!

How are you lighting the scene? It may be reflections of the HDR or of an area light.
