I'm following the old tutorial on Alcugs,...but, it doesn't seem to be working. Basically I'm trying to keep the sunlight from shining on the inside of a inside area. I've tried using exclusive group too, but the damn sun STILL lights up stuff in my inside area.

EDIT: Later.....
Well I deleted the softvolume.
But the reason the Exclusive grouping wasn't working was my fault. I forgot to go into Materials and tell it to be exlusive too.
