Some of my favorite windlight presets are from Strawberry Singh, Chic Aeon, and Luna's. Of course, everyone NEEDS Torely's Windlight presets. Installation instructions are on this Wiki Page. There are many, many good windlight presets out there for you to use, run a simple search and you will find them!
I will keep adding more over time, so keep checking back!
