I don't even know how computer animation works, honestly, and I don't need to.
I started at Pixar the month Monsters Inc. came out.
I was an animator for a while early on, but a 2D animator.
There are characters that become more popular as we fall in love with them.
There's some real dark days where you just feel like the story is falling apart in every one. Just keep moving forward, even when you are bluffing, even when you don't quite know what is going to happen next.
No one ever tells a story to help you figure out where to go when a door closes on you.
