I know right. Let’s talk about that.
As soon as you turn manual metering mode on you’ll see different lighting components getting broken here and there. I even reported black reflections caused by skylight when using manual metering mode, using the bug report form, and they confirmed the issue, and said that is not something they’d be trying to fix for now but thanks for reporting it! which basically means = physical lighting in UE4 is not something they made for people to use. It’s just going to be there for the sake of being able to say UE4 has physical lights regardless of if it works or not. I can list a bunch of problems with UE4 physical lighting right here, but why would I do that if they’re not listening? Basic issues such as not having physically based lighting makes me wonder if we should continue hoping for some high end dynamic GI haha.
