I’m talking about things like [Merida’s eyes being all buggy when animating Brave](https://www.youtube.com/watch?v=4405qEhBmEM) or [everyone’s hair going in weird directions in The Incredibles](https://www.youtube.com/watch?v=Y_MQnH54XaA) or [Shrek’s arms suddenly getting really long](https://www.youtube.com/watch?v=UNngNiYXuVE). Why does the animation fail in (apparently) random and uncontrollable ways?
In: Technology
A large amount of the animation is not initially done pixel by pixel by the artists. Instead, there are 3d models that are created with a rendering engine to give it rules on how to move. Things are given skeletons and joints and movement rules, and then the large scale movements are programmed in and all the smaller detail is generated by programming.
Bugs in that programming create weird scenarios where things just go haywire. Often its little math/logic errors that when iterated frame after frame after frame create a giant compounding problem.
