# UniUnlit

### **UniUnlit**

大概是 `UnLighting` 的缩写，即 `Unlit`。

####   
**U​nlit**

将以 glTF 的 [KHR\_materials\_unlit](https://github.com/KhronosGroup/glTF/tree/main/extensions/2.0/Khronos/KHR_materials_unlit) 扩展形式保存。

#### **可以在 Unity 中导出为 Unlit 着色器**

> **顶点颜色**  
> 只有 `UniGLTF/UniUnlit` 支持顶点颜色。
> 
> - 如果 Mesh 包含顶点颜色
> - 并且 Material 被判定为 `Unlit`，
> 
> 在导入时将应用顶点颜色。如果在不需要顶点颜色的模型上应用 Unity 的 `Unlit `系列材质并导出，那么在下次导入时，颜色可能会意外改变。在这种情况下，通过在导出时启用 `RemoveVertexColor`，可以导出不包含顶点颜色的 `Mesh`。
