Character Rigging

Character Rigging

Use this skill when building Video Production Buddy rig_plan artifacts or renderer input for local 2D character animation.

Proven Patterns

• Keep runtime code generic; make each character a data package.
• Split characters into independently transformable parts.
• Define pivots in the same coordinate space as the artwork.
• Store constraints on moving parts to prevent impossible rotations.
• Keep layer order explicit; do not rely on SVG source order after generation.
• Start with one view and add views only when the shot list requires them.

Rig Package

{
  "character_id": "mouse",
  "rig_type": "svg_rig",
  "parts": [
    { "id": "body", "kind": "torso", "layer": 10 },
    { "id": "head", "kind": "head", "layer": 30, "parent": "body" },
    { "id": "arm_right", "kind": "limb", "layer": 40, "parent": "body" }
  ],
  "joints": {
    "head": { "pivot": [320, 180], "rotation": [-20, 20] },
    "arm_right": { "pivot": [390, 310], "rotation": [-70, 95] }
  }
}

Quality Checklist

• Every moving part has a pivot.
• Every child part has a parent where hierarchy matters.
• Mouth shapes are separate assets or separate path groups.
• Eyes and pupils are separate when gaze needs to change.
• Props are separate if the character touches or carries them.
