Second time poster long time reader. Generally I've found what I need to know from reading through other issues. I couldn't find anything helpful this time.

Here's the goal. Create a few AO passes that have some objects casting AO but not receiving. In Mantra this would be done using "Object Scope". In Arnold you would use "Trace Sets". I'm not finding anything similar in Karma/Solaris. I'm curious how you all might do this?

The only solution I could think of is creating multiple AO AOVs. I attached a scene as an example. Let me know your thoughts! Thanks!
