Red9 StudioTools have been born out of frustration at Autodesks reluctancy to add some of these core features and workflows into Maya itself. Why OpenSource, well I want to give something back to the industry as I feel damn sorry for studios without the benefit of a large R&D department to craft pipelines around them. The Studio Pack is designed to speed up a modern animation pipeline.
