Apparently, you're missing the point. You probably don't know shit about building a nuclear reactor either. Does that make it an art? I never said anything about 2D being “better”.
You were acting like people who model all know how to draw and base everything they do off of drawing and therefore drawing is more important to their job than modeling.
That's an awful defeatist attitude. One I don't happen to share.
Pixar films are an art that everyone in the world can achieve if they follow they're dreams because we're all special creative people.
