Rig Deformation Test Agent

A rig that breaks in certain poses can ruin many shots before anyone notices. When a rig is updated, this agent runs a standard range-of-motion test. It poses each joint through its full range, plus combined poses like a deep crouch or an arm raise with twist. It renders each pose and checks for mesh intersections, volume loss at elbows and knees, stretching textures and controls that flip. It compares results with the last approved rig version to catch new issues. Problems go to the rigger with frames and joint names. After fixes, it reruns the full test. The lead approves the rig for production. Edge case: a costume piece with its own rig is tested together with the body, not alone.
