Shadow catcher keeping Reflections/Illuminations

Hi, I am rendering the following:

But I wanted to remove the floor keeping the shadows, so I've used the shadow catcher:

But this also removes all reference to the reflections and illuminations:

I wanted to achieve removing the floor but keeping everything else. Is something like this possible?:

Using R23 & PR6 on Catalina

Thanks

Hi,
have a look at the render Layer technique:

Thanks, that's really really handy to know.

I've got as far as this, but I cannot get the shadow layer to show:

Use Black Shadows, it will keep all shadows from the current render layer,
even without a shadow catcher.

Then compose these 2 passes.

Or update to 2020.2 and use "layer shadows" instead of "black shadows".

Thanks, I tried checking 'black Shadows' but didn't see any difference. Would it show in the live viewer?

I should have mentioned I am using Octane X PR6 (Catalina)

Hi atoyuser1,
I’m on PR7 Big Sur, but it should work also with PR6 Catalina version.
Please have a look at this example scene and report back, thanks:
