We present a facial deformation system that adapts a generic fa-cial rig into di®erent face models. The deformation is based on labelsand allows transferring speci¯c facial features between the generic rigand face models. High quality physics-based animation is achievedby combining di®erent deformation methods with our labeling system,which adapts muscles and skeletons from a generic rig to individualface models. We describe how to ¯nd the correspondence of the mainattributes of the generic rig, transfer them to di®erent 3D face modelsand generate a sophisticated facial rig based on human anatomy. Weshow how to apply the same deformation parameters to di®erent facemodels and obtain unique expressions. Our goal is to ease the char-acter setup process and provide digital artists with a tool that allowsmanipulating models as if they were using a puppet. We end withdi®erent examples that show the strength of our proposal.
