The big money, if it can be called that, in the 3d digital world is mostly in animation. I know a guy who freelances his animation skills out to some studios and has been making over $100,000 a year. He also does 3d anime (animated japanese adult stuff) on the side for some adult websites, and has been making good money doing that too. I don't know where he gets the time, but his work is very good. That's my reason for wanting to learn how to animate. I got bills to pay! hehe.
