What problem does it solve? Creating 2D character animation requires structured rig data—parts, pivots, layer order, and rotation constraints—that generic runtime code cannot infer on its own. This Skill provides proven patterns and a rig package schema for building OpenMontage rig_plan artifacts and renderer input for local 2D character animation. ## Core Features & Use Cases - Data-Driven Rig Packages: Define each character as a JSON data package with independently transformable parts, explicit layer order, and parent-child hierarchies. - Pivot and Constraint Definitions: Specify pivots in artwork coordinate space and rotation constraints on joints to prevent impossible poses. - Quality Checklist: Validate rigs with rules covering pivots, hierarchy, mouth shapes, eye/pupil separation, and detachable props. - Use Case: When building an animated mouse character for a Remotion or GSAP-driven scene, use this Skill to produce a rig package defining body, head, and arm parts with pivots and rotation limits, ready for deterministic frame-driven rendering. ## Quick Start Ask the AI to build a character rig package for a 2D character with a body, head, and arms, including pivots and rotation constraints for each moving part.
