2. Setting Details
PotaToon materials are divided into four types: General, Face, Eye, and Gem.
- General: The default type, used for most parts of the character such as the body, clothing, and hair.
- Face: Recommended for facial surfaces and eyeballs to ensure proper shading and detail handling.
- Eye: Designed specifically for pupil-only meshes. If the eyeball and pupil are not separated into different submeshes or materials, use the Face type instead.
- Gem: Designed for crystal/glass style materials with transmission, refraction, and sparkle controls.

Main Settings
| Name | Description |
|---|---|
| Main Tex, Color | Defines the color of the lit areas. |
| Shade Tex, Color | Defines the color of the shadowed areas. |
| AO Map | Designates areas that should always remain dark. However, these areas will still receive light from spotlights or other light sources. |
| Shadow Mask | Excludes selected areas from shadowing using a mask texture (R channel). |
| Shadow Mask Reverse | Inverts Shadow Mask behavior (white excludes instead of black). |
| Clipping Mask | A mask texture used to clip unnecessary parts of the mesh. |
| Base Step | Controls the shadow threshold. To ensure smooth blending with character self-shadowing, it’s recommended to keep this at 0.5 unless special adjustments are required. |
| Step Smoothness | Controls how soft the shadow edges are. |
| Receive Light Shadow | Toggles receiving the default light shadow from the brightest scene light. |
