Hey all, I originally posted this over at Railworks America but I thought I'd share it here too

I have been working the past few weeks on improving the 3D weather system introduced in Train Simulator 2015. I have finally reached the point that I am happy enough with the changes to show everyone what I have done.
This mod aims to improve the color of the sim and create a more realistic effect than the default 3D weather system.
Main Improvements include:
-Much more blue and realistic sky
-More prominent clouds
-Larger sun and moon
-Higher contrast and saturation
-Darker shadows
-More intense rain
-Darker nights

Please let me know what you think. I hope to continue improving this mod as I believe there is still a lot that can be done with SilverLining.
An update to the mod to fix some odd moon lighting at night
