Just found out about this French-made animation <https://en.wikipedia.org/wiki/I_Lost_My_Body> which was shown at Cannes 2019, and won the “Nespresso Grand Prize”. I mention it because its trivia page at IMDb <https://www.imdb.com/title/tt9806192/trivia> says “Created using the free open-source software Blender”. Note that it is not a typical 3D graphics animation: it is (mostly) drawn/rendered in a style that looks like traditional 2D cel animation. Blender has a feature called the “Grease Pencil” that lets you combine 3D and 2D-style art into the same workflow. This goes beyond simple “toon shaders” as found in other 3D software, to actually let you draw brushstrokes in 3D space, as geometric objects in their own right.
