Blender Animation (Keyframes, Mocap, Game Clips)

Handles Blender 5.x keyframing, mocap retargeting, and baking/exporting game-ready animation clips.

What it does

  • Writes Python keyframing code against Blender 5.x's new data model: Action → slots → layers → channelbags → F-curves (including the fact that action.fcurves is gone).
  • Walks through a studio workflow: blocking → breakdowns → spline → polish → review.
  • Enforces game-animation rules: one action per clip, matching first/last loop frames, root motion separation, no bone scale animation.
  • Runs bundled scripts for loop pop/hitch checks (loop_check.py), control-rig → export-skeleton baking (bake_action.py), and mocap retargeting (retarget.py).
  • Covers NLA strips, the asset-based pose library, and keying shape keys, materials, and custom properties.

Who it's for

  • Game animators exporting Blender clips to Unity, Unreal, or Godot.
  • Technical artists retargeting Mixamo/BVH mocap onto custom rigs.
  • Developers automating animation generation and batch baking with Python.

Example uses

  1. "Check whether my Walk action loops cleanly" → reports per-bone pose pops (deg/m) and speed hitches across the seam, with --fix to re-key the last frame.
  2. "Retarget this Mixamo FBX onto my Rigify rig" → auto bone map, sub-0.1° error retarget, optional in-place clip, then root motion.
  3. "Bake my control rig's IK and constraints onto the export skeleton" → one baked action per clip plus muted NLA tracks so FBX/glTF export every clip.

Install the skill I found on AI Skill Mart.
Copy the skills/blender-animation folder from the GitHub repo EL4CTEO/blender-skills into my ~/.claude/skills/blender-animation/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/EL4CTEO/blender-skills.git && mkdir -p ~/.claude/skills && cp -r blender-skills/skills/blender-animation ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/EL4CTEO/blender-skills.git
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r blender-skills/skills/blender-animation ~/.claude/skills/
  5. Optionally add the companion skills: cp -r blender-skills/skills/blender-core blender-skills/skills/blender-character-rigging ~/.claude/skills/
  6. Restart Claude Code and try a prompt like "check my walk cycle loop in Blender" to trigger the skill.
  7. Prerequisites: Blender 5.x installed (docs target 5.2); scripts are run via blender --python.
