I am writing a report and presentation on Autodesk Motionbuilder, something I have never looked at before. After looking at some videos and Tutorials, some of them mentioned that they use characters made in Maya and then apply animation in Motionbuilder. Am I wrong in saying that? If so, then what is the difference between Maya and Motionbuilder? Do I need to install Maya in order to use Motionbuilder?

If anyone knows of any links on any good training material such as books, dvd's, videos, etc.. on Motionbuilder that would be so great!
