Get arkit from blendshapes_calculator, and generate arkit csv file to drive metahuman

[cx47]

I generated the arkit csv file from blendshapes_calculator. By using the arkit csv file to drive the metahuman to generate animation of the metahuman. But the result of matahuman face animation performed unnormal shaking. However, I used live link face to drive the metahuman live face, the animation performed normally without shaking mentioned before. Could anyone help me, why this unnormal shaking happened? Thank you very much!
