Absolute black shadow takes forever to render with custom shadow catcher node 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. 

Thanks!
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.
