I did this awhile ago but I thought I would share it now. So I made these Piercings:
It works on any player model as long as you keep the 4 pixels -where the rig is- skin colored.
You can re-color it by just going into the "Piercing RIG" file and changing the skin texture in the top left corner.
The set that I have made include:
One Industrial piercing, One Helix piercing, One Orbital piercing, One Upper lobe and two regular ear-lobe once.
You can customize the rig however you want (add more, take away some and what not), I don't really care. But just please don't re-upload and if you're using it for like a picture I would love to see it .
