We take a brief tour through the history and topics of some of the most important studio-sponsored open source projects used in VFX and animation production. Where do they come from? Who is involved? Why are they important? We also discuss why it is in the best interest of studios to not only use open source, but also to sponsor and contribute to these projects, and how getting involved with these projects is a great way to explore the more technical aspects of studio production.
