Watch coco's friend Melody who was the first popular western vtuber
https://youtu.be/0uwXV_ntcgU?t=760Fun fact - melody was an indie at the time and had better 3d tracking than cover or Nijisanji or many other corporate vtubers at the time
So coco really wanted cover to push their 3D tech as well. The max she could manage was better hip tracking and doing summersaults.
She also tried investing in proper home 3D but dropped it saying it would more than a year's rent for her.
