Comprehensive Overhaul for the weather in Morrowind, Solsthiem, and beyond.

The README mentions that tweaks need to be made to cloud speed (or else they move *really* fast!), see below for those....

Use the contents of the Skies - .IV folder in the zip file. The Particles/meshes/raindrop.nif and Particles/textures/tx_raindrop_01.dds files must be deleted, they are not compatible with OpenMW at this time. Read the included Readme.txt file for information on the available installation choices.

Below are the values that need to be changed and their default settings:

fallback=Weather_Clear_Cloud_Speed,1.25
fallback=Weather_Cloudy_Cloud_Speed,2
fallback=Weather_Foggy_Cloud_Speed,1.25
fallback=Weather_Thunderstorm_Cloud_Speed,3
fallback=Weather_Rain_Cloud_Speed,2
fallback=Weather_Overcast_Cloud_Speed,1.5
fallback=Weather_Ashstorm_Cloud_Speed,7
fallback=Weather_Blight_Cloud_Speed,9
fallback=Weather_Snow_Cloud_Speed,1.5
fallback=Weather_Blizzard_Cloud_Speed,7.5

And the edited values are below:

fallback=Weather_Clear_Cloud_Speed,0.25
fallback=Weather_Cloudy_Cloud_Speed,0.4
fallback=Weather_Foggy_Cloud_Speed,0.25
fallback=Weather_Thunderstorm_Cloud_Speed,0.6
fallback=Weather_Rain_Cloud_Speed,0.4
fallback=Weather_Overcast_Cloud_Speed,0.3
fallback=Weather_Ashstorm_Cloud_Speed,1.4
fallback=Weather_Blight_Cloud_Speed,1.8
fallback=Weather_Snow_Cloud_Speed,0.3
fallback=Weather_Blizzard_Cloud_Speed,1.5

You can paste these just after the last fallback= line in your openmw.cfg file.
