Opaque Alpha for Refractive Material

Corona Corona for 3ds Max Help Required

I have a refractive glass material in my scene and naturally it has alpha with shades of grey. Is there an option to render the alpha of that certain glass material as (white) opaque. (If I remember the name correctly; like the Transparency Propagates Alpha Channel option in Mental Ray.)

Image shows: Go to “Advanced options” of the material → “Alpha mode” (switch to “Always white”)

Good Luck

Thank you all. Esp. Frood for writing down what is in the image.
Cause I couldn’t see the image in external link either.
I don’t know why I can’t see embedded images. The same in Chrome and IE.
