Well, I'm not a mesher, but I tried. Here is a set of derivable horse hooves, made from mittens, with an opacity map so that the thumbs are 'ghosted.' There is a cuff to it, and I put fur texture there to look like a fetlock.
DEVS: IF YOU DERIVE FROM THIS PRODUCT do NOT remove the cuff, I had to derive from mittens that have no skin underneath, and added an opacity map. If you remove the cuff you will be able to see straight through the entire hand.
