For my graduation project I created a modular auto rigger in Maya. It's inspired by different autoriggers found online, and 3dBuzz's Modular Rigging Systems with Python tutorial. Using mutarig, I did the setup of all the character rigs that were used in the production of Exhume and Between You and Me.
During its use in production, the system was thoroughly tested and a lot of improvements were made. As a final exam I designed a weird mutant creature (shown in the video) to proof virtually anything can be rigged with mutarig.
