Glass

[glorybound]

I have used V-Ray's glass, and other glass materials, even from scratch. I have also tried to reset V-Ray

i reuse my "standard setup" often , so this is a "safe State" ... if this fails merging the hole Scene into a new one helped me, when there is no visible solution... ( also when vray reset don`t work )
Sometimes strange things can happen.
Strangest thing i had was deleting an Object that was baked after that into every Viewport and was also visible in the rendering ( this was not selectable and not in the scene list anymore)... merging helped to remove that ... a month later an 3dsmax update came out ...which fixed this bug i saw in the buglist
