Bump on glass ignored

[Jonish]

Hello,
After two years of constant struggle I need to ask about bump on glass:

If the surface is facing camera with its backface, bump is ignored. If the bumpy glass surface is located behind a flat glass, the bump is ignored.

Is there a way how to make it work on V-Ray 3.6?

Image attached, front-facing glass on the left, back-facing glass on the right. Front glass is standard clear glass.

Thank you for your help

Jonas

Apologies for the late reply!

Would it be alright if you send this sample file to support@chaosgroup.com to check the set up in our environment? If so, please send us an archived copy (V-Ray > Pack Project) via email or a file-sharing service of your choice.
