mascot-logo-reconstruction

MCP backend

Use when: Brand mascot/logo 3D reconstruction, exact part counts, texture-driven model matching, repeated “does not match reference” feedback, or full pipeline coordination across analysis, contour mesh, registration, UV fitting, validation, animation, and export.

Before the first Blender call, read ../text-to-blender/references/mcp-backends.md. Prefer official MCP for shared capabilities; preserve the selected backend for the whole task. Tool names in recipes are client/legacy examples: map them through that reference and its agent-host guide.

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
