In a previous post titled Creating a Deforming Control Geometry Setup, I walked through the process of using a combination of wrap deformers and blendshapes to create an intuitive animation interface for the mouse character Robyn. That was the actual structure we used during the production of the Animal Facts short, but as many people have mentioned — too many deformers can cause Maya to slow down.
Another very interesting technique was mentioned to me by a few folks, and based off great information from Charles Wardlaw, Raveen Rajadorai, and a post by Harry Houghton, I’ve put together a demonstration on another way to achieve a similar effect without the use of these deformation nodes.

In this case, we’re using a transformGeometry node to help take the shape of the deforming object and use it to drive the control. Very cool!
