Is there a quick way to assign an AOV to an Arnold Sky object so I get a matte for that upon render?
I have a scene of a port with a ton of objects. I'd like to have a matte for the Arnold Sky object for possible compositing effects, but assigning an Object Mask to that Sky object does not generate a matte for me. Activating the background AOV doesn't work, either.
The only way I'm seeing to isolate that sky would be to add Object Masks to the scores of other objects in the scene. This doesn't strike me as a very efficient workflow.
Any thoughts? Thanks!
