## What it does

This skill resolves silhouette mismatches by reshaping mesh boundaries directly against texture masks. Rather than stretching UV layouts over flawed geometry, it adapts the 3D surface to the source artwork in front X/Z projection. The agent executes these edits via a connected Blender MCP backend.

The procedure pairs mesh edges with source contours using landmarks or arc-length metrics. Interior vertices then shift through thin-plate spline deformation or piecewise-affine warping. Local coordinates remap into atlas bounding boxes, which prevents texture bleed without manual UV repainting.

Fitting must occur before adding mesh depth or extrusion. If front silhouette acceptance gates fail, look-dev stops immediately. The bundled script `scripts/contour_correspondence_report.py` verifies bounding box center, scale, and contour deltas.

```

2. **Manually: put the files in place**
- File: `~/.claude/skills/texture-driven-mesh-fitting/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/texture-driven-mesh-fitting/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add RobLe3/cc-blender-skill --skill texture-driven-mesh-fitting -a codex
```

2. **Manually: put the files in place**

## When to use it
- align source-locked mesh boundaries with texture-atlas contours
- stop texture bleed across 3D model silhouettes in front view
- warp interior mesh topology using thin-plate splines or landmarks
- measure contour deltas via `scripts/contour_correspondence_report.py`

## Example prompts
- Reshape the current mesh boundary to fit the decal contour in the atlas, using landmarks `base_left` and `base_right`.
- Deform interior vertices with thin-plate splines to match the source mask and remap UV coordinates.
- Run `scripts/contour_correspondence_report.py` to compare object silhouette deltas against the source mask.

## MCP backend

Use when: Texture-driven geometry fitting, mesh boundary fitting to atlas masks, UV-preserving contour correspondence, point/landmark deformation, source mask to mesh repair.

Before the first Blender call, read [../text-to-blender/references/mcp-backends.md](../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.
# Texture-Driven Mesh Fitting

This skill fixes the common failure: a texture is mapped correctly, but the mesh silhouette underneath is wrong.
The mesh adapts to the source contour; the texture is not stretched to hide a wrong mesh.

## Preconditions

- Structural parts are segmented (`source-part-segmentation`).
- Each part has a contour/mask and, if textured, an atlas region (`atlas-uv-fitting`).
- The object is source-locked in front X/Z before depth is added.
- Canonical view policy is resolved (`multiview-constraint-solver`) if views conflict.

## Workflow

1. Extract source contour from the texture/wireframe region.
2. Extract current mesh boundary in the same projected coordinate space.
3. Build ordered contour correspondence by arc length, named landmarks, or seam/control points.
4. Move boundary vertices to source contour positions.
5. Move interior vertices by smooth interpolation, piecewise-affine warp, or thin-plate-spline style deformation.
6. Preserve UV parameterization by remapping boundary-fitted local coordinates into the atlas rectangle.
