## What it does

The skill sets an order of work: mass and planes first, surface last. The agent builds the blockout and primary forms headless through `scripts/bx_sculpt.py` — smooth-blend `Clay`, plane cuts, numpy brushes. Client-quality finish happens with Blender's real brushes in a live session via `bx_gui`: Clay Strips, Scrape, Crease Polish, Smooth.

Planes here are stated, not hunted for. The gonion, chin bottom and cheekbone get a point and a normal, and `plane_cut` / `corner_cut` carry them onto the mesh. If re-cutting planes still leaves a face that reads as a ball, the problem sits in the mass, so you rebuild the jaw block instead of cutting again. Resolution stays low as long as possible, and symmetrize runs after every remesh.

The skill expects scenario-blender-expert to be installed — that one covers the execution channel, the review loop and the 5.2 API changes. If it is missing from your available skills, the agent asks you to add it or proceeds from tool schemas and flags the gap. Without a live GUI session you are limited to the headless blockout; brush-based surface work does not happen that way.

## Requirements
- Works with: Blender

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-blender-sculpting -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-blender-sculpting -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/scenario-blender-sculpting/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-blender-sculpting -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/scenario-blender-sculpting/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install scenario-labs/skills scenario-blender-sculpting
```

2. **Manually: put the files in place**
- File: `.github/skills/scenario-blender-sculpting/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-blender-sculpting -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/scenario-labs/skills --path skills/dcc/blender/scenario-blender-sculpting
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/scenario-blender-sculpting/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-blender-sculpting -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/scenario-labs/skills/tree/HEAD/skills/dcc/blender/scenario-blender-sculpting/SKILL.md

## When to use it
- block out a head or bust from primitives without ending up with a ball
- state the gonial angle and cheekbone plane as point and normal
- fix a jaw that reads like a balloon
- plan remesh and multires resolution stage by stage
- reproduce Clay Strips, Crease and Scrape moves without a tablet

## Example prompts
- Block out an adult male head from primitives at voxel H/40
- The jaw looks like a ball — check the mass and rebuild the jaw block
- Do the surface finish with Clay Strips and Scrape in a live bx_gui session

# Sculpting (heads and characters, Blender 5.2)

Expert sculpting is structure first and surface last: masses blocked with stated planes and corners,
proportions locked at low resolution, every stage judged by eye through a long lens, and appeal as
the final test, not the mesh numbers. The agent builds blockout and primary forms headless
([`scripts/bx_sculpt.py`](scripts/bx_sculpt.py): smooth-blend `Clay`, plane cuts, numpy brushes) and
does client-quality surface work with Blender's real brushes in a live GUI session (`bx_gui`). If a
sibling skill named here is missing from your available skills, ask the user to install it
(`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and
flag the gap.

**REQUIRED BACKGROUND:** scenario-blender-expert (execution channel, review loop, 5.2 API changes).

## Stance (the expert delta)

- **Planes are stated, not found.** Thelen cuts plane borders with Draw Sharp and re-cuts them
  whenever a face "looks off"; Naydenov simplifies into planes, then smooths; Reinhardt uses Scrape,
  Trim and Line Project for clean cuts. Executable form: give the plane (point + normal) to `Clay`
  half-space clips or `plane_cut` / `corner_cut`. A `flatten` or `scrape` dab fits its plane to the
  ball under it, so it follows the ball.
- **The jaw is a block with a gonial corner, the cheekbone a mass with its own lower plane.**
  Zarins: the gonial angle is the age and sex dial, steep in adult males; the widest face point is
  the top of the zygomatic arch. Naydenov: the cheekbone runs from the ear down and forward, only
  its lower edge shows. Thelen: bone plus tissue, never razor sharp.
```
