Title: satin glass not reflected
Post by: bango74 on 2020-06-18, 17:58:30
As you will notice the glass with glossines 0.2 in the mirror is not reflected, how do I solve the problem?

This is a known issue. I had the same problem a few days ago.
I don't know, what the best workaround could be, to be honest..

Make the mirror reflection glossiness 1.0  or enable caustics in the frosted material.

Probably everyone has differently. I don't have the latest version of Cinema and Corona and I'm out of luck ;-)

...but when you turn on the caustics, everything is fine. Weird...

It's a known issue:

- Appearance of refractive materials changes when reflection glossiness other than 1 is used (even if it's set to 0,999). The workaround here is to enable caustics for the refractive material.
