Vmcomix minecraft rig setup for BVH motion capture

The rig Comes from this source. the version with no smoothness

So I been working on trying to get this rig set up for use with bvh files. I have the Make human Addon that makes it so you can just use the rigify rig. But seeing how I cannot delete some of the preexisting bones this has caused some issues. At times the head will not move with the mesh at other times the mouth and eyes will not go along with the rest of the body resulting in something out of a cthulu fanfic.

Rigging was something I always had difficulty with. I was hoping someone could get it to work and then tell me what they did so I can apply this method on my own

I’m trying to make a web series and I have some motion capture software (brekel) rigging the model is the big issue atm.
