This tutorial took me half of the day to make. I was so confused and found many mistakes that I had to fix. To make sure, I had to make bones and check options about 4 times...
BUT! It's finally done. I hope it's not that confusing though, I tried my best.
Plugin download: p.tl/mQ3y-
This tutorial was based a bit off SelfishNeko's youtube tutorial for Upperbody bone. But I wanted to check out ALL the options, so I made this tutorial for you. It's useful.
I hope it helped~
<forgot to metion> YES these bones rig automatically, but you'll probably have to fix rigging yourself, it's never perfect.
If you don't have "User" in your PMD, you can put plugin in "System" folder as well. But if still the plugin is not showing in PMD, maybe you'll need to download newer version than 0.6.3 PMD.EDIT!
The 6th box where I said it's center bone, it's in fact GROOVE bone! My bad, sorry. I didn't notice the difference, but now I see you can add with this plugin a groove bone :F
