16km visibility,Visual spotting affected by fog value

[Kaleunt]

I use the original 16km visibility mod with the Seeadler's cloud fix integrated by miself ( i stay with the default reflexions and sea colors,
just a question of personal taste). The mod is really nice and the new visibility improve really the sim. But with the new visibility values we
are loosing this real life effect of the horizon blur at extreme range, an
effect well rendered in the standard game. So i explored the scene.dat file
and i have found that the fog distance value was tweaked. I reintregated
the horiginal fogdistance value in the 16km Scene.dat file and the horizon blur came back. But something found to be just an eyecandy tweak
appears in fact to affect the detection capabilty of the crew to detect
an another object at long range, this effect as also en influence on your
potential to see another object.
Maybe something to adjust to obtain realistic spotting capabilities, at night
for exemple.
