One of the concerns of the animators is linking the members of the character together. This helps the animator to better control the character. As such, when the hands are linked to the head and then back to the chest. In these cases, there might be an unwanted jump that we corrected with the script.
And the result was quite desirable. This technique can be used on any character. Just create multiple nodes in the character and then execute the script. At first there were a lot of bugs that were solved over time.
