Problem with glossy glass material and reflection in a mirror

I have a big problem.
I wont to use a HDRI in my scene. I build a window with glossy, milky glass. But in the reflection of the mirror left from my window the HDRI is shown normaly not with the milky glass refraction.

Plese Help !

This is a known issue, but at this point I do not think I can offer any workaround. I will notify my C4D colleagues.

For the C4D team - this is already logged and acknowledged by the dev team.

Hi, If you keep your mirror’s glossiness at 1 it should work just fine.
