I downloaded the rain and snow decal with the snow segment along time ago. I tried to search for it for you but can't seem to find it again. I'll upload it here for those who want it. The person who made this has a read me file with instructions. Follow them and it will work. I would give credit to the one who made this, but theres no name in the pack. Mods, if I am in the wrong for posting this, Remove it. I just could'nt find it in the search.EDIT: (I found it but the download link would'nt work. I got a 404 error)
