To turn something off you need to know what to turn off. I dont see the reasoning behind an animatior/material artist having to know how Local Exposure works and what it is.
Yeah thats the point, maybe they shouldnt activate every feature by default. I dont see photoshop or visual studio having terrible default settings, dont know why unreal sould have a free pass on this matter.
No, they are two separate things. LE has nothing to do with bloom and it can and should be used even without bloom. Is a exposure adjustment, if any it can affect the threshold of bloom intensity values, but it shouldn’t break bloom.
