I've done this with a tree in a snow scene and it worked out pretty well. Duplcate the object that you want the snow on and then raise the duplcate just a little and resize it some. Then put a snow texture on the duplcate. You'll have to adjust the raising and resizing of the duplicate to get the amount of snow coverage you are looking for. Also maybe sink a rock or two into the surface of the duplicate if your looking for a more lumpy coverage. For the tree I did. I also had to rotate the duplcate just a bit for it to look good. Gave it a more uneven snow coverage. I've not tried making icicles. DM
