Yes, I know. But there are plenty of student projects and even professional ones that don’t. After doing some research, it seems stationary skylights can change color and intensity as necessary, which is , so that can totally work as an ambient solution in tandem with GI.
Well, this is nicer. I think the issue I kept seeing with games (not naming names) is they just forget to add skylights and environment lights. That’s not really Lightmass’s fault, so, I’m sorry for misconstruing it.
