I have been beating my head against the wall for days trying to figure out any way to resolve this. I used metahuman animator, ran calibration takes, and processed my footage. When I load the animation to the face with no body animation it looks fine but as soon as I try to attach a body animation it is broken. 
I have followed many tutorials and fixes, I have followed elliejayliquid - blend mask but that didn’t work for me. I have also followed a JSFilms, PixelProfessor, and couple of jobutsu’s all trying at this from a slightly different angle and nothing is working!
I am trying to keep the rotation data from the performance but also use the body animations. MHA facial animations are SO great looking, I just can’t seem to work with them at all past the performance processing. PLZ help!
