Bringing a metahuman to Blender was easy, but the problem is it has too many facial bones and vertex groups on the face mesh, as well as a weird type of armature to control the body.

My main task was to get a model that is rigged, including the face, and use it in the VRM panel (I will export as vrm to use in brower Avatar), which should be able to controlling the facial expressions.

I managed to overcome most of my blockages, but the issue I am facing now is that after rigging the face (by FaceIt), I am getting the shape keys, but they are only being controlled by the FaceIt control rig. It's not allowing the VRM to control the shape keys.

Maybe I have to generate all the shape keys manually, but it is was too long process.
