I am trying to render this scene without the objects so only the shadows and reflections remain. I have a custom nodeset that separates the shadows and the reflections which is why I don't use the new Shadow Catcher.

Problem is the circled area where there is absolute black takes forever to render and I was wondering if there is a way to get past it.

I managed to fix the issue with this node set. Basically it says "just don't render this area if camera rays hit it" or something like that. I don't know I am bad at answering questions but if you have the same issue, try replicating this nodeset and maybe it will help you. It helped in my situation at least. enter image description here
