Packing up some maya stuff I done in the past few months and learning 3dsMax for the coming new job.

The soft IK feature is one of many rig features I wanna to implement many years ago. It’s like all other features, not super hard and you could get it once you’re willing to dedicate to figure out what the hell the logic is. I wonder that my method may not be the best and there must be some simpler one . . . https://vimeo.com/168185968

Recently I would recommend the 8 classes of Cartoony Facial Setup by Puppeteer Lounge. They show the use of wire deformer effectively which works well for general cartoony face. For very stylized or detailed cartoony face I might stick with the general joint based method.

And I found an informative post about some recent rigging techniques !
