Hi stoianm, and a big thanks for this mod!
This is indeed a huge improvement over the earlier version.
Visibility during night at various conditions/situations works exactly as in your mod description. When the (half)moon rose up from behind the horizon, visual conditions changed gradually with increasing moon height, in a very realistic way. Also the clouds at night look very detailed with nice nuances.
One very important bonus for me is that light conditions at daylight now are realistic, too. No more exagerated dazzle from light surfaces, and daylight clouds very natural and detailed. No more details lost in dazzle like in the earlier version.
Definitely a keeper!
OMG - so many words, but they are well deserved!
