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。

Matcap

存放大量Matcap用的球形环境贴图。

Outline

Textures

存储一些默认贴图与一些测试用（无用）贴图。
