Double glass wall with foil renders improperly

[grzegorz_moniak]

Hi,
i have problem with rendering simple double glazed glass wall with private foil on it. On one side it renders correctly, and other side looks like black strip. Can't figure it out
Materials are glass from deflault gray library, and blurred glass as a blend material with glass and mask. File attached
Vray 4.20.3

Hi grzegorz_moniak,

Your glass objects don't have any thickness. While using Fog Color, it is best to add some thickness to the objects, as its main purpose is to to simulate the fact that thick objects look less transparent than thin objects, by specifying the attenuation of light as it passes through the material.

In the recorded example, you will see that if I reset the Fog Color you'll be able to see the bricks instead of those strips. Alternatively, if the Fog Color remains and I add thickness to the planes, the black strips will now render correctly - http://ftp.chaosgroup.com/support/sc...1_15-28-44.mp4

Hope this will be of help. To read more about Fog Color (and check some examples), please visit: https://docs.chaosgroup.com/display/...ColorParameter
