Oh, and H.sie's instructions say to have the following done to one's sensor.cfg file which I have done. I have not tried adjusting the setting in the Hsie.ini file.
Maybe that's the slider you're thinking of.



19. Night Vision Fix (by Makman94, Rubini, h.sie)
This fix addresses the so-called „Vampire Night Vision Bug“: In a clear but dark night, your Uboat watchcrew can see a ship in 15km distance, while an enemy warship watchcrew cannot see your Uboat in 300m distance (at least in GWX). This hardcode fix eliminates this problem. Not only the watchcrew has lowered visible range, also the player on his monitor,
since the mod changes the rendering of the objects at night using a simple environmental hack: A fog-curtain is moved, depending on the sun position. At daylight, the fog curtain is not changed, but as soon as the sun hides behind the horizon, the fog-curtain is continuously moved closer to the Uboat. So the balance between the players eyes and the watchcrews eyes is widely kept.
Per default, the fix reduces visibility at dark night about 50% (factor 0.5), but this factor can be adjusted in the hsie.ini file. Set the value e.g. to 0.75 in order to have a 25% reduction of visibility at night.
Recommended Crew Sensor Settings in data/cfg/Sensors.cfg (tentative values):
· Visual range factor = 0.5
· Visual fog factor = 1.02 (see below!)
· Visual light factor = 0.8
The „best“ Visual fog factor depends on the chosen environment and your monitor settings and must be individually fine-adjusted between approx. 1.00 and 1.05. If your crew detects a ship at night, before you can see it through the binocular on your monitor, the Visual fog factor must be slightly enlarged and vice versa.
