Scene overexposure

I follow the learning documents
“Extend Default Luminance Range In Auto Exposure settings”. Check the box.
But the scene is clearly too pale
Seems to be overexposed
I tried adjusting the time(CesiumSunSky),But it didn’t have much effect
Is my method good? What else do I need to pay attention to?
Thank you!

You can reduce the intensity of the DirectionalLight under the CesiumSunSky.

But also, make sure you restart the Editor after enabling “Extend Default Luminance Range In Auto Exposure settings”. Sometimes the setting doesn’t apply until after a restart.

Thank you very much. Your suggestion worked!
I really want to know, is the time on CesiumSunSky real?

The sun position based on date and time is realistic, but don’t assume that it precisely corresponds to UTC.

That would be great. Thank you very much
