i have a problem regarding Cryptomattes. Unfortunately, I cannot share the scene.
The light source of the scene is an Octane Daylight with Fog Medium activated.
With Fog Medium activated the Cryptomatte pass is unfortunately unusable.
Without Fog Medium the result is as it should be. See comparison picture.
Apparently there was this bug also in the standalone version.
This was probably fixed in version 2020.2 RC 4.
" Fixed cryptomatte passes rendering incorrectly when environment medium was enabled."
Here are a few pictures to illustrate:
