A basic look at using deformers from our old friend Stuart Christensen where he shows how deformers can be used for modeling and for animation as well.
“Basic Geometry deformers are great for creating parts for models, squishing heads or creating undulating blobs moving about in space, not to mention a million other uses! Get some hands on experience with using deformers in this tutorial by Stuart Christensen. Imagination once again is key to using deformers to create interesting movement, parts and effects. Play around with deformers for a couple of hours and you will become hooked on using them for all sorts of stuff. Enjoy!”
