This part involves the splitting of the joints and the joint design of the wings. I divided them into many parts. At the beginning, I added a ball to each part of the joint, but I found that it seemed too complicated, and if I guessed too much, it would destroy his integrity. Because this part had a wing membrane, the final presentation effect would be too broken due to wisdom. So I removed some unnecessary joint parts, but it made him look more flexible as a whole, and the sports meeting was more reasonable. I adjusted the size of the joint ball and the position of the joint ball for a long time in this part determined the joint. I also adjusted his steering and movement amplitude for a long time. His size is not a very simple project. This requires many debugging. After testing the joint ball to cut them, I still need to rotate to determine his range of movement and whether there will be a volume collision.
