There is mGear for Maya and Rigify for Blender! Me as a self-taught rigger always prefer to learn how to build a custom rig from scratch and then develop a tool to implement it. However lately I have been trying out these autorigger tools and I would say if you are already familier with the concept of rigging and comfortable with it then feel free to use these tools to assist in production. I don’t however recommend these tools to beginners who are getting started with rigging and want to make a career out of it. Take your time to learn the basics, build your own custom rigs and then learn from these tools 🙂

2D Bugs Bunny rig demo by Stephen Iosun. Very impressive!

I have never thought that rigging in Blender would be so much fun! It opens a whole new possibilities of cartoon rigging. Here I experimented with creating a cartoon spine rig with limited number of controllers which is the primary of goal of puppet creation, keeping it simple. If you find it interesting and would like to learn to rig in Blender check out Puppeteer Lounge training workshop programs.
