Hi jojorender, yes you’re right neither C-sun is realistic, but better than C-sky.  
As you said a solution could be to use area lights with directionality.

I showed the yuoutube tutorial to Corona support team and they said that it’s actually a clever solution and a technique used in film industry for matte painting creation. 😅

This is the best I have gotten!

Thanks edoardo\_explorer,  
changing the corona light “directionality” to imitate sun light doesn’t really work for me. Doesn’t look realistic at all.

Maru, is this the wrong place to ask for help?  
Do I need to open a support ticket for this? If so, is there someone in the support team that knows how lighting interior shadow catcher in C4D works?
