I have a MMD character that I want to make the animation of easier through generating a rig with Rigify.
The unique problem is that this character must remain MMD compatible even after a rig is generated. This means: the bone’s of this character must not added/removed/renamed/repositioned/reweighted/re-parented in order to retain their compatibility(so the animation on their bone’s can be exported and easily re-applied to other characters that share the same MMD bone-set).
An older 2015 solution to this is(using the google translate website translation): https://kaerudokoro.netlify.app/blender/mmd_rigify/ however as the pitchipoy armature in rigify seems to be no longer a part of rigify, I receive an error when trying this in blender 2.79(the version the code in the website is written for) stating that the pitchipoy architecture could not be added.
Does anyone know of a solution(ideally in blender 2.8) to integrate a MMD rig with a rigify armature?
