This mod has 1 goal, making sure that STLM looks good for all weather conditions.

For that, i worked in two ways:
 - Tweaks of weather conditions
 - Tweaks of clouds files

I recommend using Motion Blur Toussaint mod (STLM Version), as it fix a problem with B&W clouds (causing performance issue with SLI or multiple screen or any big config). I'm too lazy to include this fix in Custom Clouds....

Main features

for clouds:

 - Fixed/reduced lots of exposure problems for almost all clouds, all weathers, all zones.
 - Addition of many clouds to make custom modifications for each weathers / zones.
 - Sun looks better behind clouds.
 - More contrast with clouds at sunset.
 
for weathers:

 - Added clear weather (WT_Clear) in weather cycle for all zones.
 - Added light clouds weather (WT_Light_Clouds) in weather cycle for WO, Novigrad/Velen and KM.
 - Changed weather probability of occurrence to include WT_Clear and WT_Light_Clouds, keeping the spirit of Vanilla.
 - Same combination of clouds as Vanilla for almost all weathers/zones.
 - Added B&W cloud in Skellige clear weather (WT_Clear).
 - Fixed missing cloud in Mid_Clouds for WO.
 - Increased wind for clear weather (WT_Clear) to avoid flat sea.
 - New Bigger waves for Skellige during storm.
 - New Fixed Vanilla bug with rain_mist emitters in rain_storm_fx (better compatibility with bigger waves).
 - New Fixed invisible rain by switching low rain with rain from B&W at WO, Skellige and KM.
 - Update Added forest_leaves FX effect (80% probability) (without dust) for Rain_Storm (Skellige, Novigrad/Velen) and Heavy_Clouds (WO and KM).
 - Update Added ice particles FX effect from the mod Skellige Ice Breath for Mid_Clouds (20%), Heavy_Clouds (40%) and Mid_Clouds_Fog (60%) for Skellige.
 - New Added dust particles FX effects (with different probabilities) for WT_Clear at WO and Novigrad/Velen.
 - Update Added foggy weather (WT_Mid_Clouds_Fog) for WO, KM (small probabilty) and Skellige (medium probability).
 - New Better foliage/water color consistency between bad and good weather for all weathers / zones.
 - New New bad weather env for WO.
 - New Fixed yellow clouds (from Volumetric Clouds) at Skellige for Heavy_Dark_Clouds weather.

Miscellaneous:

 - New Reduced overexposure dawn at WO.
 - New Reduced specular grass (grey, white grass) for WO and KM.
 - New More DOF for bad weathers.

for FX effects (ZZZFX):

 - Increased numbers of particles (X2) for ~1500 FX effects (water, quests, cutscenes, dust, signs, monsters, animals, spells, characters, environment, gameplay, weapons etc..)
 - Cover all the game and DLC.
 - Compatible with Better FX, Improved Particle Systems and Brutal Bloods.

It's optional and can be used with any lighting/weather mods.


There are 2 mains versions (use only one):
 - Custom Clouds and Weathers for STLM 3.2.
 - Custom Clouds and Weathers Less Wind for STLM 3.2 based on the mod More Realistic Wind Effect.
