>completely FUCKED up face
Use face mods.
>broken finger
that's an issue with blender fbx exports and/or unity fbx imports. Unity and blender have a different direction for xyz axes so it's got some bullshit with small bones. Also unity can't do trig properly so angles often get fucked. I've never had to fix the finger bones for any of my literal hundred+ so werks on my masheeen I guess.
>hips/spine/shoulders
Still don't even know what this issue is either but I hear it a lot. It doesn't need to look good on the inside, only when in use.
CM3D2 is MMD tier easy but if you want perfection then just make your own models from scratch.
