How to rig a face 3D model?

To rig a face 3D model, you create a skeletal structure (joints/bones) for key features, bind the mesh to these bones, and add controls to animate expressions like smiling or blinking. Focus the skeleton on areas that drive expressions—jaw, eyebrows, eyelids, mouth corners—so moving a bone deforms the face naturally. Binding (skinning) links the mesh to bones, while controls (sliders/handles) simplify animation by grouping movements (e.g., one slider for both eyebrows). For beginners, try Blender’s free auto-rig tools for basic face rigs—practice animating simple expressions first to get comfortable with how bones affect the mesh.
