Since there’re massive factors involved in animation development, automate the process may not be possible via a single animation engine (need to do a thorough review :P). Instead, automatically puzzle existing tools together may be more practical. Because we could get out the most of each tool. For example, if tool x is the best in painterly style, tool y is the best for animating, they are golden combination to produce film z, then it’d be nice to efficiently transfer the result between each other.
