Glass looks transparent and mirror reflects the scattered beams. Nice if it rendered much faster.

Can you upload a scene that shows the problem, with steps how to reproduce/what is off exactly?

Yes, I can upload the scences later and where possible describe reproduction steps.

Somehow materials got stranger with every change or use in the blender file used for the scenes above. A good reason, to start with a new blender file and define objects and materials from scratch. ...wat? Well, to test my hypothesis of the screwed file I've appended the new objects to the old file...

Now, glass is close to expected and experienced behaviour again. (It seems like material definitions c...

Behaves as random or sobol regarding glass.

CPU BiDir, random. (With path I don‘t see much of the laser beams in scattering medium.)

It happens at least for glass with sobol too, but it is a bit slower for these scenses.

What ever happens here it fits not to my expections and experiences with glass and mirror in real life. There must be something wrong with the implementation of the interaction of scattered light with surfaces of some material settings. Glass: Rough or Architectural works, default not. Glossy: Rough...

One can see glossy transluscent scatters light on the surface and let light 'pass' to a certain depth.

I guess this paper describes a more practicable method for a denoiser.

This is a very good information. I usually set the gains until I like the result with lower resolution and restart the render with higher resolution.
