I think holding “shift” while toggling the upper level of hierarchy in a collection (any of the toggles; holdout, indirect only, and so on) will take care of toggling all “children” collections inside.
I’m watching these on mobile right now so I can’t quite test it, so I’m sorry if my memory fails me.
If that’s right though, I still think it’s good to toggle it open to double check it happened as expected. No one likes to waste render time and I can totally see myself messing up the set up.
On another note, very excited for this course! I found very tricky to find good information about render passes and proper workflows with After Effects and am looking forward to build a better foundation on these concepts and, even better, be able to do it all without leaving Blender!
