Animation Quality Gate

Validate Blender animation attempts before accepting them by rendering contact sheets, checking silhouette stability, flicker, framing, subject dominance, layer separation, export compatibility, and motion-design coherence. Use after animation renders or when the user says motion/morph/outside elements look bad.

What this skill tells the agent

Animation Quality Gate

Do not accept an animation because it rendered. Accept it only after a contact sheet and failure analysis pass.

Review dimensions

  1. Subject dominance — the main asset remains readable and is not overwhelmed by HUD/context.
  2. Layer separation — base subject, texture state, glow, HUD, and background are separate enough to control.
  3. Silhouette stability — silhouette stays constant unless deliberate morph is specified.
  4. Texture coherence — no ugly full-image crossfade, crop pop, or unregistered morph.
  5. Motion coherence — arcs/dots have a reason, restrained speed, and coherent easing.
  6. Export truth — the final export can reproduce the effect or limitations are explicit.
  7. Frame aesthetics — sampled frames look good as stills.

RALPH trigger

If a user calls an animation ugly/bad, stop rebuilding immediately. First:

  • collect preview frames/contact sheet;
  • identify the failed dimension(s);
  • invoke quality-refinement-autoloop if the stack lacks a method;
  • add/refine generic skills only after sanitization;
  • only then rebuild the animation.

Hard gates

  • No final animation without a contact sheet.
  • No GLB claim for texture swaps implemented only with Blender Python handlers.
  • No decorative context elements in base avatar export unless requested.
  • No morph that violates locked geometry constraints.

Scripts

  • scripts/animation_contact_sheet.py builds a contact sheet and frame-to-frame difference report from rendered frames.

Blender Animation

Animate objects, cameras, lights, and properties in Blender — keyframes, F-curves, easing (Bezier, Linear, Sine, Bounce, Elastic), shape keys (morph targets / blendshapes / visemes), drivers (Python expressions on properties), NLA actions for reuse and layering. Use whenever the user asks to "animate this", "make it move / rotate / scale over time", "add keyframes", "loop / oscillate", "shape key / morph / blendshape", "visemes for lip sync", or any time-based property change. Make sure to use this skill even if the user does not say "animate" — also covers "spin it slowly", "make it wave", "fade in / out", "pulse", "facial expression".

Blender Cameras

Set up Blender cameras with cinematic intent — focal length, depth of field (f-stop / focus object), composition (rule of thirds, leading lines), animated cameras (orbit, dolly, push-in), tracking constraints. Use whenever the user asks to "set up the camera", "frame the shot", "make it look cinematic / hero / portrait / wide-angle / telephoto", "add depth of field", "orbit the camera", or any composition/framing request. Make sure to use this skill even if the user does not say "camera" — also covers "hero shot", "close-up", "from above", "shallow focus", "85mm portrait look".

Blender Export

Export Blender scenes to glTF/GLB (web/AR), FBX (game engines), OBJ (universal), USD (VFX pipelines), STL (3D printing). Includes per-format settings, embed/unpack textures, axis conversion, polygon optimization (Decimate), and target-platform validation. Use whenever the user asks to "export this", "save as glTF / FBX / OBJ / STL / USD", "package for Unity / Unreal / Three.js / web / AR / 3D print", or any output format conversion. Make sure to use this skill even if the user does not say "export" — also covers "package this for the web", "make it work in Unity", "send to Unreal", "save for 3D printing".
