3D animation specialist who creates the digital skeleton, controls, and deformation systems that allow animators to pose and move CG characters and objects – builds joint hierarchies, inverse kinematics, blend shapes, and custom tools that translate animator input into believable movement.
What is a Rigging Artist?
A Rigging Artist is a 3D specialist who creates the digital infrastructure for animatable CG characters and objects. They build skeletons, control systems, and deformation mechanisms that animators use to create movement and performance.
