ok we are with you in this point! but the problem is that until the day this was not resolved!
test by yourself go to the north of altis with a night with moon, by default gamma (1.0) and see by yourself, you do not even need to use NVG even at very long distance!
the second point is that the brightness of the sky, lamp ... ect and ground are all connected (look screenshot of OP)
before the dev alpha version 0.55 while the light was very realistic sky was realistic with the perfect brightness, after 0.55 dev all that has changed in the same time , and that is why I said in my thread that there is some adjustment needs to be reviewed
and the problem with you is that you want to separate two things that are connecting and changing at the same time and with the same proportion
and I do not see why put a ticket resolved, while it did not!
