MMD Bone Reference Charts make MMD Model-making Easier!

When making a model from scratch, knowing what to name your bones is one of the most important parts. That’s what makes it so frustrating when the only references you can find are hidden in the comments of a submission on deviantArt . . . or worse, hidden in a file on someone’s stash where you can’t favorite it.

To remedy this, I’m plopping down the bones right here.

After creating those bones, you are able to mirror them . . . given your model is symmetrical. If your model is not symmetrical, you will also need to add the bones from the right side of the body.

左つま先IK toe IK L
右足IK leg IK R
右つま先IK toe IK R

To figure out the best placement of the bones, it is a good idea to study a model. Be warned that the older a model is, the less likely that the bones are perfect. The Groove Bone is a relatively recent invention.

This list only truly works with PMX Editor. With PMD models, you were required to have hidden bones. Not so with PMX models.


It’s extremely important to sanitize your display panel. That is only possible with a correct list of the bone groups. The only list I could find was hidden in someone’s Stash. That meant that I was unable to favorite it to track it down easily . . . so I had to bookmark it. While that list has all of the bones that are contained in that specific group, I’m sure most people can figure out what bones go in the arm group. For that reason, I’m keeping it simple and only posting the names and notes for the groups that make less sense.

I hope this was helpful – I know that I would have been a lot happier while making my first model if I had found this handy page!
