I work as an illustrator, and I have not had any problems following instructions from my employers, as long as it's through text. Then again, I don't really know how much our jobs differ. When I'm the only one person working on a project, instructions can be a bit looser. I know that as an animator, you'll have to follow instructions very carefully in order to make your work fit in with everyone else's. Which, I guess, would make text-communication even more important.
I haven't had to disclose my aspergers to any coworker or employer, but I always ask that communication happens via email. I haven't needed to give any other explanation than "it's just easier that way". No one has ever questioned that, but if they did, my explanation would be "because I can send pictures in an email". That's a pretty big advantage if your work is visual.
Luckily text-communication is completely normal these days, and it's so much easier for me to get every detail of the instructions through an email. I would definitely screw up if I were to get verbal instructions.
