For Brave, the team at Pixar had to deal with a hero or rather heroine, who is on screen for almost every shot, but who needed wild, yet beautiful hair. The simulation department needed to develop a technique and ,the Princess Merida’s hair was almost a three year process to get correct. Earlier hair such as for the characters in The Incredibles had much more groomed hair, but here the character’s hair simulation needed to solve how to get this messy, tempestuous and unpredictable look while still looking attractive and flowing nicely with the animation.
