Object visibility in another objects shadow/reflection

[dzapski]

Hello
I wonder how to setup Object/tag to not to be visible in another objects reflection/shadow.
I had tried to find solution on forum, and place an plane with octane tag (camera visibility 0) to stop reflection cube on metal plane, but the results was not good.

In attachment you can find SS where i marked the reflection/shadow which I Want to disable on a brushed metal object. But also keep black cube with glossy material
Any idea how to fix this?

Try it with render passes and some masking methods.

It will rotate on animation

Yes but you can use object masks also. I can't think another way.

Are you talking about Object Buffers? Thank you

A lot of passes would help here. See marked stuff and choose one of them.
