question city lights at night

The areas I'm flying over are terrascened and there are lots of nighttime lights. It looks good in clear weather, but if I go into "weather/other", and reduce the visibility to, say, 2 miles, Fly renders the ground night lights as visible for far too much distance.Basically the ground itself disappears around 2 miles out, and so do runway lights, but the ground lights are still visible 15 or 20 miles out it seems. It looks pretty weird to see lights all around an airport, but not the airport lights themselves until you get much closer.Anyone know of a way to adjust the night texture fog penetration? There looks to be a parameter to do it only for runway lights in fly.ini.John/madmax
