## ShadingModels
|
||
采用CustomNode构造FMaterialAttributesde的之后传递到MaterialAttribute模式的材质中，其他骚操作还有：
|
||
1. 使用宏开启MRT5：`#define PIXELSHADEROUTPUT_MRT5 1`
|
||
2. 设置ShadingModelID：`Result.ShadingModel = 14;`
|
||
3. 使用FToonShadingPerMaterialCustomData ToonShadingPerMaterialCustomData（位于Common.ush)来传递卡通渲染用数据，之后在BasePassPixelShader.ush中将数据塞入GBuffer中。

## Effects
|
||
- **MF_EdgeLight**：边缘光效果，通过UE菲尼尔函数以及一些贴图、变量实现效果。主要被***MF_CharacterEffects***引用。
|
||
- **MF_Dissolve**：溶解过度效果。主要被***MF_CharacterEffects***、***MF_SceneEffects***引用。
|
||
- MF_Fur：用于制作Fur效果的材质函数，被**ToonShading_Standard_nooffset_fur**引用。主要还是靠***GFur插件***，没有参考意义，升级难度+1。
|
||
|
||
