Vray 3.4 - Transparent glass for postproduction, help needed
-
Hi All
in V-ray 2.0, PNG output, glass materials were transparent by default, so it was easy to insert background in post production.
How to set it up in 3.4?Thanks!

Well, it didn't do what I meant.

I think I wasn't clear enough before. I want my render output to have reflections and refraction on glass materials, but still be transparent so I can easely import background image. Do I have to use layers (render elements) now to get that?
Thanks!

Chaos people solved this for me: A recommended workflow to achieve transparency of glass in a .png image would be to adjust the settings of the glass material. In the 'Refraction' rollout, change the 'Affect channels' parameter to 'Color + alpha'.
