# Animation Shader Skill

Domain knowledge reference for animation-style shaders (Toon Shaders). Contains preset styles, feature lists, and reference mappings for popular shader libraries.

> [!NOTE]
> This skill contains **domain knowledge only**, not a workflow. Pair it with a workflow skill (e.g., OpenSpec, SpecKit) or an agent's plan mode for structured design flow.

## Usage Modes

### With Workflow Skill (Recommended)

When used with a workflow skill (e.g., OpenSpec, SpecKit) or in the plan mode of an agent, this skill serves as a domain knowledge plugin:

- **During requirements/spec phases**: Use the Presents section to identify the target style and map user requests to concrete feature sets
- **During design/planning phases**: Use the Feature List to look up all relevant `references/` documents for each feature
- **Key rule**: For each identified feature, read ALL reference files listed — do not select just one

### Standalone

A lightweight `workflow-standalone.md` is also available as a self-contained design pipeline if needed.

### Knowledge Mode (Query)

When user requests to query knowledge for animation shaders, this skill provides preset styles and feature-to-reference mappings based on the task.

## Presents

Use these presets when the user is unsure about specific features or wants a quick starting point for a specific style.

*   **Features**: PBR (Metallic/Smoothness), Normal Map, Shadow Ramp, Subsurface Scattering (SSS), Outline (Inverted Hull).
*   **Use Case**: Modern action RPGs, high-end cinematic characters, "Genshin-like" but more detailed.

*   **Description**: Recreates the look of classic cel animation from the 90s.
*   **Features**: Color Adjustments (High Saturation, Posterization), 3-Tone Shading (Double Shade), Outline (Inverted Hull), Film Grain.
*   **Use Case**: Nostalgic projects, retro-style games, lo-fi aesthetics.

### 7. Oil Painting / Artistic
*   **Description**: Simulates traditional media like oil painting or watercolor.
*   **Features**: Brush Stroke Textures, Distorted UVs, Sketch / Paper Overlay, Smudged Shadows, Sketchy Outline.
*   **Use Case**: Storybook visuals, artistic showcases, dream sequences.

### 8. Flat Pop Art
*   **Description**: A bold, graphic style with minimal shading and vibrant colors.
*   **Features**: Base Color / Main Texture (Unlit), Outline (Inverted Hull), Halftone Overlay, Stencil Patterns.
*   **Use Case**: UI characters, music videos, stylized indie games.
