I've always hated how blizzard was more like hail. Big chunks of ice just falling down. I wanted something softer and snowier. Here is my submission:
I wish the snow could be thicker but blizzard only spawns so many shard models so the coverage is limited. The first picture is a close up directly in the center of the blizzard.
Instructions:
1) Download the mod from:
Snowey Blizzard.MPQ
2) Move the file to World of Warcraft > Data
3) Rename the file patch-x.MPQ (replace x with any number 3-9 or number a-z)
4) Play wow and enjoy.
This file does not require the model editing fix file to run. It works just like it is.
