Lumen and auto exposure

Can any Lumen experts help me understand exposure?

A simple scene with a directional light, and skylight and Post Processing Volume with Min Max exposure set to 1.

However when I zoom in some type of auto exposure compensation seems to be happening and my rock assets brighten up dramatically.

Is this something to do with Lumen or?



Dude, I have the same problem with my scene.

I have disabled auto exposure in the project render settings and also have the min/max = 1 in my Post Processing Volume. I’ve attached a video and screen shots of settings for reference. I also noticed that it has to do directly with the Directional Light set to Movable. When it is set to static, the issue goes away (obviously this is undesirable as it completely breaks the lighting with Lumen.)
