This week, I mainly added skeletons to the cloak and refine the skin weights.
Initially, I added 8 skeletons to his cloak. After discussing with Sean and Yann, We reached a consensus view that there were too much and it was inconvenient for the animators to animate.
And then we deleted 4 of them and distributed them equally in space to achieve basically the same size of the range they control. Furthermore, because the chest part of the cloak was rarely about to move, we omitted the upper part of the skeletons and connected them to the joint of the belly part.
With the help of Sean, I also added some circles(controls) and made them establish a parent-child relationship so that as the father joint rotates, the child joint will follow along.
Finally, I erased some irrelevant weights, for example, the joints of the chin may not affect the movement of the clothes, etc.
