renderman would be the "renderer" they used. They actually developed that renderer I belive. It is highly customizable by the production house using it as well. The movie was really amazing. It never ceases to blow me away at how good they are at writing stories. I suppose that if a movie is going to take 5 years to make, you don't make it based on a crap screen play. The director was the same dude that directed Iron Giant. I think he proved that there is none better to put this movie together. I also liked how they showed a family working together as a family unit. Nice to see something positive for a change when it comes to the "average" family. :) Cheers, Joe
