Zootopia’s Fur Technology


The team comprising directors, engineers and animators spent about eight months studying animals. They went to San Diego's Safari Park, Disney's Animal Kingdom and all the way to Kenya to observe their movements and mannerisms. But to make the characters look like their real-world counterparts, they needed an up close and personal look. The crew ended up at a Natural History Museum, where they studied fur under a microscope and even brought in lighting setups to see how the strands reacted to light.

Simulating the texture and density of animal fur is a daunting task for any animation studio. The last time Disney worked on a furry character was in Bolt, eight years ago. While the studio managed to create a soft, white layer of fluffiness on the superhero dog, the same tools wouldn't work for the 800,000 mammal variants in Zootopia.

To make the animals look realistic, Disney's trusty team of engineers introduced iGroom, a fur-controlling tool that had never been used before. The software helped shape about 2.5 million hairs on the leading bunny and about the same on the fox. A giraffe in the movie walks around with 9 million hairs, while a gerbil has about 480,000 (even the rodent in the movie beats Elsa's 400,000 strands in Frozen).
