Digital Video, the makers of the 2D animation software Toonz, and Japanese publisher DWANGO have announced that as of March 26 Toonz will be made open source under the name OpenToonz.

Studio Ghibli has been using Toonz for animated features since 1995 when it needed to seamlessly combine digitally painted and hand-drawn animation for Princess Mononoke. OpenToonz will use the Toonz Studio Ghibli Version and include features developed for the studio over the course of their many years using the software. Atsushi Okui, Executive Imaging Director at Studio Ghibli, has said in a statement that “We are happy to hear that this open source version contains the Ghibli Edition. We hope that many people inside and outside of the animation industry will utilize this software for their work.”
