Check out this great course from the Gnomon Workshop that will give you the basics of Facial Blendshape Modeling.
The Gnomon Workshop has released Introduction to Creating Facial Blendshapes in Maya, a complete guide to facial blendshape modeling in Maya and ZBrush, recorded by Digital Domain artist Derrick Sesson. The workshop, which comprises over five hours of video training, explores how to apply the movie-industry-standard Facial Action Coding System (FACS) to facial animation work.
This workshop assumes you have no prior knowledge of blendshapes, and takes you through the full facial process using Autodesk Maya. Derrick starts with a thorough explanation of FACS (Facial Action Coding System), before preparing a ZBrush head for deformation, breaking down essential shapes needed for each region of the face, and blocking in those shapes with deformers, such as clusters. He shows how to refine those shapes with Maya’s sculpting tools, before bringing them all together into a blendshape node.
The concepts and lessons in this workshop will equip you with a fundamental understanding of FACS and how to create blendshapes, providing you with all the skills you need to create a set of facial blendshapes that give you the control to morph a face into any expression you like.
