Make object not reflect on selected object in Arnold?

[litote]

Is there a way when rendering with Arnold to make one object not be reflected on the surface of another particular object? I know you can make an object not appear in all reflections universally, but can you specifically pick and choose certain objects to only be reflected on other specific objects ? You can do this in Cinema 4D.

Hi!

You could try Trace Sets (works per material and not per Object):

Hello,

Thanks for the link. I can't work out how to use Trace Sets form the sketchy info. Is there a tutorial somewhere?
