The Story Behind Stuart Little's Fur

Rob Bredow, executive creative director and head of ILM, has recently joined Befores & Afters to discuss working as an animator lead on Stuart Little at Sony Pictures Imageworks two decades ago.

Simulating fur was not an easy challenge, of course, so they had to find a clever solution that could work. Doing photorealistic CG characters was a relatively new thing and they were developing new solutions.

"We came up with this hack in the shader that steals the lighting from the diffuse lighting of the skin as its initial lighting component. That’s what the base of the fur is lit by, and then as you get more towards the tip, it fades to a more accurate cylindrical shading model," said Bredow "You have controls in there for how much of that you want to use. It ended up looking pretty realistic even though it was a complete hack."

That's an amazing story you have to read. You can find the full version here.
