What problem does it solve? Character animation often fails in production due to collapsing joints, foot sliding, broken loops, or bad retargeting. This Skill provides a structured workflow to rig, retarget, generate, and quality-gate character animation so it deforms cleanly and behaves predictably in the target engine. ## Core Features & Use Cases - Rig Specification and Authoring: Define skeleton naming, hierarchy, twist bones, facial scope, root, and retarget profiles before generating weights and clips into preserved working copies. - Deformation and Motion Validation: Review stress poses from multiple views and validate root motion, contacts, foot sliding, loop continuity, additive assumptions, and engine import. - Seven-Gate Production Sign-off: Enforce rights and consent checks, format validation, visual consistency, runtime budgets, playability smoke tests, regression evidence, and human approval before production use. - Use Case: A game team needs to retarget motion-capture clips onto a new character for Godot. The Skill inspects the mesh, defines the retarget profile, generates validated clips, and produces a contact and loop report with provenance records. ## Quick Start Use the rig-animation skill to rig this character mesh, retarget the walk and run clips onto its skeleton, and verify deformation, foot contacts, and loop continuity for engine import.
