Ignore certain values when setting the post process quality

Hello there,

in my game there is an option to change the post process quality. However when I change the value to a low number (sg.postprocessquality=1 or 0), the nighttime of my game turns completely black.

I have a strong feeling that this is due to the “Auto exposure” is being turned off. Now I want the player to have the option of changing the PP-Quality, but the auto exposure should be spared. Is this possible?

Thanks in advance.
