Why is Lyra so DARK?

I have 2 identical maps. I thought it was Lumen but it isn’t. Global Illumination is off on both. And it doesn’t appear to have any difference in Post Process in the map (except see below). Both are UE 5.0.3. So what else could it be? It must be a project setting Lyra has that differs from a default project? Examples:

Left: Lyra, Right: Regular

Just sky with nothing else in it

The only thing I noticed (just now) is Lyra on the left says EV100 rather than Brightness. I’m guessing that could be it, but what is it?

UPDATE: I’m pretty sure it is that, but what is it, and how would you recommend approaching it? Setting EV100 to 0.0 seems like Brightness 1.0 …so far. (Almost always find a solution after I post :smile: It’s like some sort of magic forum!) But I wonder what it’s doing, and if that’s enough.

Sounds like it makes it more camera-like…

Changing to 0 as mentioned seems close enough to my original.

Enabling Extend default luminance range option in Project Settings changes Brightness to EV100.

“EV100 refers to an exposure value using an ESO or film sensitivity of 100. The lower the exposure value, the brighter the image will be. Higher EVs produce darker images. EV represents the f-stop and shutter speed. An EV of 0 represents an f-stop of 1 or a wide open aperture and a shutter speed of 1 second producing a bright image as more light is allowed in over a longer period.”

Typical EVs
Home interior: 5-7
Office space: 7 or 8
Outdoor sunny day: 15
