For animators working with free and open source software, nothing compares to Blender. A fully-featured 3D animation suite, it offers a huge array of tools that individuals and small studios need: modeling, rendering, motion tracking, and more.
Volunteers power Blender. Artists, visual effects artists, and hobbyists alike contribute to the tool, facilitated by the Dutch Blender Foundation. Now, that same group of volunteers is planning to create a feature length 3D animated film called Gooseberry, and they’re seeking help via crowdfunding.
