Control Rig - how to improve character's deformation
summary
Pipeline shows concrete rigs and math that shipped to a game engine and worked in production for Cyberpunk—extra joints and simple constraints reproduce muscle volume and twists at runtime. Examples: 3 extra forearm twist joints with 100/50/20 rotation distribution, five elbow fillers plus a forward-moving pair to prevent collapse, a spline (quadratic) shoulder curve and aim/point/balance constraints. Maya node graphs get reimplemented as ordered custom nodes in engine with LOD pruning (face ~250 → ~20 → head only) and acceptable performance.
