Mascot / Logo Reconstruction

This is the top-level skill for 1:1 brand mascot reconstruction. It chains the specialized skills and enforces stop/go gates.

Harmonization requirement

For mascot/logo work, use blender-skill-harmonizer first when multiple source types or validation failures are present. It sets canonical source policy and prevents conflicts between reconstruction, UV, fit-repair, lighting, export, and animation skills.

Skill chain

1. reference-analysis-validator — source inventory, manifest, part counts, masks.
2. orthographic-registration — shared front/side/back/top coordinate contract.
3. contour-to-mesh — structural meshes from measured silhouettes.
4. atlas-uv-fitting — per-part texture/UV fitting.
5. blender-materials / blender-lighting — only after geometry and UVs pass.
6. reference-analysis-validator again — overlay gates before export.
7. blender-export — export only after gates pass.
8. blender-animation — only after static model is accepted.

Non-negotiable order

Static reference fidelity comes before animation and beauty rendering.

measure → manifest → contour meshes → depth registration → UV fit → overlay validation → export → animation

Hard gates

• expected structural part count equals Blender scene/export structural part count.
• front silhouette overlay passes threshold.
• face/features landmarks pass tolerance.
• side/back/top renders match their registered envelopes.
• texture atlas regions are mapped per part.
• optional aura/background is separated from base structural GLB.

Modeling guidance

• Treat mascots/logos as designed symbols, not natural objects. Symmetry is not guaranteed.
• Do not infer hidden leaves/petals from radial math.
• Avoid primitive-first construction when a silhouette exists.
• Use semantic object names and validation prints.

Source-manifest structural part invariant

Create exactly the structural parts declared by the source manifest. Extra background arcs, glow, aura, shadows, guide marks, and decorative rings are context/decor unless the manifest explicitly promotes them to structural geometry.

Front-plane rotation rule

In this Blender coordinate convention, the front camera looks along the Y axis and the reference silhouette lives in the X/Z plane. Therefore 2D rotations inside the front view are rotations around the Y axis, not around Z. Use rotation_euler = (0, angle, 0) for 2D component orientation in the front projection. Z rotation spins objects into/out of screen-space incorrectly for X/Z-plane meshes.

Output contract

Every final reconstruction folder should include:

• reference_manifest.json
• registration_report.json
• atlas_regions.json
• validation/front_mask_validation.json
• validation/front_overlay_reference.png
• named .blend
• base .glb
• optional aura/context .glb
• BUILD_NOTES.md with pass/fail gates
