|
||
- MF_DecodeArrayIDAndAlpha：分离输入浮点数的整数与小数部分。整数部分作为TextureArrayID，小数部分作为Alpha参数。

||
- [x] ***CameraLightCollection***：各个角色的主光照颜色、边缘光颜色与主光亮度以及LightDir。
|
||
- MF_CharacterMainLightIntensity：使用CustomNode编写的函数，通过RoleID进行Switch Case计算对应角色的MainLightColor * MainLightIntensity，这些一般在Sequence中进行修改。
|
||
- MF_ApplyToonHairSpecular：头发高光计算，被M_ToonBase_V02调用。

|
||
## 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**。除此之外`/ResArt/CommonMaterial/Materials/V02/MatCap/`也存储了Matcap贴图。

# Materials

>所有角色与新服装都迁移到V02版本，V01已废弃。
|
||
|
||
- Special
|
||
- M_BeiLa_Skin_AnotherWorld：特别定制的材质。
|
||
- [ ] V02
|
||
- Special
|
||
- M_NaiLin_AnotherWorld02：特别定制的材质。
|
||
- ***[[#M_ToonBase_V02]]***：**默认的ShadingModel为13**，也就是SHADINGMODELID_TOON_BASE。
|
||
- ~~M_ToonBase_V02_Test~~：测试用，主要的差别是使用的是MF_ToonBaseInput（里面用的是旧版的MF_Surface）
|
||
- MI_ToonBase_V02：
|
||
- MI_ToonSkin_V02：
|
||
- MI_ToonFace_V02
|
||
- MI_ToonHair_V02

|
||
- [x] **M_Eye_Highlight**：
|
||
- M_Hide：隐藏模型用材质。
|
||
- [x] M_Penetrate：
|
||
- [x] **M_ToonBase_V01**：主要的逻辑是MF_ToonPBRInput => MF_CharacterEffects。**默认的ShadingModel为14**，也就是**SHADINGMODELID_TOON_PBR**。
|
||
- [x] M_ToonBase_V02_Penetrate：带有Penetrate功能的M_ToonBase_V01。
|
||
- [x] **M_ToonFace**：
|
||
- [x] M_ToonFace_old：
|
||
- [x] **M_ToonHair_V01**：
|
||
- [x] **M_ToonSkin**：
|
||
|
||
## M_ToonBase_V02
|
||
与M_ToonBase_V01相比。最主要的逻辑区别在于：
|
||
1. MF_ToonPBRInput => MF_ToonBaseInput_V02
|
||
1. MF_Matcap_Add => MF_Matcap。不输出Specular，转而将高光结果输出在BaseColor与Emissive中。
|
||
2. MF_ToonPBRShadingModel => MF_ToonBaseShadingModel。
|
||
1. 移除Specular
|
||
2. 增加ToonShadowSmoothness
|
||
3. 增加ToonSecondaryShadow
|
||
4. ShadingModel为13，也就是**SHADINGMODELID_TOON_BASE**。14 => 13。
|
||
2. 增加MF_ApplyToonHairSpecular()计算头发高光并且将结果叠加到Emissive上。
|
||
3. 增加Penetrate逻辑，结果加上WPO上。
|
||
4. 增加Refraction逻辑，通过Normal以及菲尼尔节点插值，以此设置Refraction。
|
||
|
||
# MaterialInstance
|
||
|
||
# Outline
|
||
主要存储了Outline主材质以及所有角色所用到的Outline材质，统一放到对应角色文件夹中。描边材质使用***M_Outline_V03***或***MI_Outline_V03***即可。
|
||
|
||
1. 材质ShadingModel为Unlit、BlendMode为Maskd。
|
||
2. 所有描边材质都有**MF_CharacterEffects**、MF_CharacterMainLightIntensity。所以都支持溶解效果，以及调整每个角色的描边光照效果（连接的是材质Emissive引脚）。
|
||
|
||
- M_Outline_V01 & M_Outline_V02：
|
||
- **WPO**引脚逻辑：**描边粗细控制部分逻辑**和V01基本相同，除了V01有Minimum Line Thickness这个粗细最小值。剩下的其他逻辑一模一样。
|
||
- ***M_Outline_V03***：
|
||
- **OpacityMask**引脚逻辑：与V01、V02略有不同。会将BaseTexture贴图的a通道乘以HideMask，然而并没有材质使用。
|
||
- **WPO**引脚逻辑：V03版本的**描边粗细控制部分逻辑**做了更加合理的改动。VertexColor的RGB通道代替Backface外扩时的VertexNormalWS，这样不会影响光照效果。
|

- MI_Outline_V03

- MI_Outline_Face_V03
