## What it does

The skill tells the agent that 3D on Layer is a chain of runs, not one call. Every stage has its own `filter.use_case`: `text_to_3d` builds a mesh from a description, `image_to_3d` from concept art, `remesh` cleans topology and cuts polygon count, `retexture` lays down new surfaces, `rig` adds a skeleton and weights, `animate` adds motion. Each stage takes the previous stage's `file_id` as input.

When the design is settled, the skill points you at the image path first: approve a still with `layer-image`, then spend on the 3D run. The reference should be clean — subject on a plain background, even lighting, three-quarter view. Heavy shadow reads as geometry, so a dramatic key art frame gives you a warped mesh.

Before running anything, name the target. `quad_mesh` for assets you will sculpt or deform later, a `face_limit` matched to the platform, `pbr_materials` and `include_textures` for lit scenes. Skip the textures and you get bare geometry that looks broken in an engine. Rigging a mesh generated in an action pose does not work — generate the rest pose first and animate into the action. Thin parts like chains, straps and hair come out fused, so plan to model those yourself. 3D runs are expensive, so check the price estimate and ask before proceeding.

## Install

### Claude Code (native platform)

```bash
npx skills add layerai/skills --skill layer-3d -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/layer-3d/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/layer-3d/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-3d -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/layer-3d/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-3d -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/layer-3d/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install layerai/skills layer-3d
```

npx skills add layerai/skills --skill layer-3d -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/layerai/skills --path skills/layer-3d
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/layer-3d/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add layerai/skills --skill layer-3d -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- generate a 3D mesh from a text description
- turn concept art or a reference image into a model
- cut polygon count and fix topology
- apply PBR textures to an existing mesh
- rig a character and add animation

## Example prompts
- Turn this approved prop concept into a game-ready mesh for mobile
- Remesh this model and bring the polygon count down
- Rig this character in a neutral rest pose

# Layer 3D Generation

## Overview

3D on Layer is a chain of separate use cases, not one call. Generate the mesh, then remesh, retexture,
rig, or animate it as the deliverable requires. Each stage is its own `filter.use_case` and its own
run, and each takes the previous stage's output `file_id` as input.

| Stage                            | `filter.use_case` | Input                              |
| -------------------------------- | ----------------- | ---------------------------------- |
| Mesh from a description          | `text_to_3d`      | prompt                             |
| Mesh from concept art            | `image_to_3d`     | `init_image` or `reference_image`  |
| Cleaner topology, lower count    | `remesh`          | `init_mesh`                        |
| New surfaces on an existing mesh | `retexture`       | `init_mesh`, often `texture_image` |
| Skeleton and weights             | `rig`             | `init_mesh`                        |
| Motion on a rigged mesh          | `animate`         | rigged `init_mesh`                 |

The loop and the spend gate are in the `layer` skill. If a sibling skill named here is missing from
your available skills, ask the user to install it (`npx skills add layerai/skills --skill <name>`);
unattended, proceed from tool schemas and flag the gap.

## Start from an image

`image_to_3d` is the stronger path whenever the design is settled or settleable. A generated mesh
inherits its silhouette and surface detail from the reference, so approving a still first with
`layer-image` costs one cheap image run and removes most of the iteration from an expensive 3D one.

The reference image should show the subject clean: isolated on a plain background, lit evenly, in a
three-quarter view that reveals depth. A dramatic, heavily shadowed key art frame makes a worse
reference than a plain orthographic-ish view, because the model reads shadow as geometry.

`text_to_3d` is right when nothing exists yet and the shape is simple or generic enough to describe.

## Say what the mesh is for

The engine target changes the request, so state it rather than accepting defaults:

- **Topology**: `quad_mesh` where the asset will be sculpted, deformed, or subdivided downstream.
