Models don't matter to me. I use a Luka Montecore that I already have characterized in Mobu, and it works well for me to adapt the Vmd movements to Genesis 8. The facial expressions are not transmitted, since they are morphs of the Pmx or Pmd. You have to generate them with the anilip or another, with the synthesized voice of Vocaloid. It takes work, but the results are better than through 3dXchange, as they can only create a Daz-compatible BVH, and a 6000 frame animation can take two hours to load ..
later, I pass it in Alembic to cinema 4d ..
The good thing about MMD4Maya is that it renames the bones with the Autodesk HIK nomenclature, which in Blender sometimes fails. (Almost always ..) That simplifies a lot.
