## What it does

The skill runs on top of the Scenario MCP server. None of the models take a text prompt, so the source photos carry the whole art direction. A base line covers props and objects, a Portrait line handles human heads and busts, each in 2.1 and 2.0 generations. Members disagree on which knobs exist and how values are spelled, so read the contract from `model_schema_get` before running anything.

Views in `images` are positional: slot one is the front, then back, left, right, all of one subject. A front view alone works, extra views buy stabler geometry on sides the model never sees. One centered subject on a plain background converts best.

Runs are slow — medians near 17 to 21 minutes, with a slow quartile past 30. A `jobs_wait` timeout is normal, so re-call with `pending_job_ids` instead of firing a second `model_run` or polling with `job_get`. `requestType`, `resolution` and `pbr` all move cost, spanning four times on one member, so `dry_run` the exact parameter set before a batch. No schema field picks the container: the catalog advertises GLB, OBJ, STL and FBX, but confirm the delivered format from the returned asset before promising an engine target.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-sparc3d -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/scenario-sparc3d/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/scenario-sparc3d/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-sparc3d -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/scenario-sparc3d/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-sparc3d -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/scenario-sparc3d/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install scenario-labs/skills scenario-sparc3d
```

2. **Manually: put the files in place**
- File: `.github/skills/scenario-sparc3d/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-sparc3d -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/scenario-labs/skills --path skills/scenario-sparc3d
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/scenario-sparc3d/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add scenario-labs/skills --skill scenario-sparc3d -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/scenario-sparc3d/SKILL.md

## When to use it
- build a watertight mesh from a single product photo
- tighten geometry with four views of one object
- get a PBR-textured asset ready for engine import
- cap the delivered mesh at a target face count
- reconstruct a human head or bust with the Portrait variants

## Example prompts
- Search Scenario models for sparc3d and show me the schema of the newest base one
- Upload this photo as asset_front and model_run with dry_run to get the cost
- Generate a mesh from four views with face 500000 and resolution 1536fast

# Scenario Sparc3D Image-to-3D

## Overview

Sparc3D, Hitem3D's image-to-3D family on Scenario, turns one to four photos into a watertight mesh
with no text prompt: the source images are the entire art direction. A base line handles props and
objects, a Portrait line human heads and busts, each in 2.1 and 2.0 generations. Discover them with
`search` and treat `model_schema_get` as the contract: members disagree on which knobs exist and how
values are spelled.

Connection and the core loop: the `scenario` skill in this repo; model-agnostic 3D work: the
`scenario-3d` skill. 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.
