Animation:Master has a LOT to offer for character animation. Part of its strength lies in it's use of splines to build its models. That being said, it does NOT play well with others. Importing and exporting is very lacking, and most people who use it create everything inside the package. As for who uses it, the man who created its most famous piece, (Alien Song,) works for Pixar now because of the imagination of this video. He of course uses their in-house software now, but still uses A:M for his personal projects.
