For XP 11.25+



This script provides dynamic haze/fog control based on reported visibility, providing smooth visibility transitions throughout all phases of flight. This means no "infinite" visibility the higher you get, no abrupt visibility changes and a realistic looking atmosphere based on reported visibility for the area.



Features:

* Smooth visibility transitions during all phases of flight

* No white out/grey out/blue out when passing through clouds or at night (My older "No White Out In Clouds" script is no longer needed)

* No more infinite visibility

* More challenge in IMC conditions

* Works with default weather (manual and real weather)



Compatibility:



* Not compatible with X-Enviro

* Not tested with Ultra weather, disabling the haze options in that plugin should get it working with X-Visibilty theoretically

* FSE v0.5 uses the older gradual visibility script in the TrueHaze.lua file. Remove all text below (or remove lines 122-288) --TRUEHAZE INTERNAL PARAMETERS and this script should work fine with FSE

* If you are using the "No White Out In Clouds" script, please remove it as it is no longer needed

Installation:

This script was tested on X-Plane 11.25, and it requires the flyWithLua NG plugin available at:

To install, place X-Visibility.lua in the following folder:

<X-Plane installation path>\Resources\plugins\FlyWithLua\Scripts\



Usage:

There is no interface but it is possible to change some parameters of this script with the following lines:



local plugin_on = true --enable plugin

local debug_info = false --show debug info

local atmoTop_visibility = 30480 --elevation to apply the max visibility, default is 30480 m

local minFog_value = 0.6 --minimum fog value between 0.0-1.0, default is 0.6

local atmoTop_Fog = 1.5 --fog value after passing atmoTop_visibility

local highAltFogMult = 1 --reduce to 0.5 or 0.25 if you feel the haze at higher altitudes is too strong, default is 1

Thanks to @SNowblind7 for his help testing this script and for his initial work in the gradualVisibility script from which this is built upon.
