Glasses with Vray and the Fog Bias Setting

Just a test.  I'm playing around with the fog bias setting in the Vray Refraction settings.  Color corrections and lens blur were added in After Effects.  The render settings are fairly low so there is alot of noise in the image.

Here are the settings for the glass material.  I used an IOR value for crystal.  It isn't great glass as you can  see but it might work as as starting point.  If you are loooking for a particular glass material, try changing the Fog multiplier and Fog bias setting for different looks.

Here is a post that helped me.  http://www.pixelab.be/blog/2008/09/14/fog-bias-parameter-test-in-vray-material/

It is from an older version of Vray but it is still useful.
