```
|
||||
|
||||
|
||||
## DeferredShadingCommon.ush
|
||||
1. 实现[[#Encode/Decode函数]]
|
||||
2. HasCustomGBufferData()函数添加对应的ToonShadingModel宏判断
|
||||
3. [[#FGBufferData新增变量]]
|
||||
4. [[#Encode/Decode GBufferData新增逻辑]]
|
||||
1. Metallic/Specualr/Roughness => ToonShadowLocation/ToonForceShadow/ToonShadowSmoothness
|
||||
2. AO => ToonSecondaryShadowLocation
|
||||
3. CustomData => ToonShadowColor/ToonSecondaryShadowSmoothness
|
||||
4. PrecomputedShadowFactors => ToonSecondaryShadowColor
|
||||
5. `#define GBUFFER_REFACTOR 0` 以此关闭自动生成Encode/Decode GBufferData代码，并使用硬编码调用Encode/Decode GBufferData。
|
||||
6. `#if WRITES_VELOCITY_TO_GBUFFER` => `#if GBUFFER_HAS_VELOCITY`，以此**关闭写入VELOCITY到GBuffer中**。
|
||||
|
||||
### Encode/Decode函数
|
||||
RGB655 to 8-bit RGB。
|
||||
将R 256 => 64 ,GB 256 => 32。之后使用2个8bit浮点来存储：通道1存储R与G的头两位；通道2存储G的后3位与B。
|
||||
```c++
|

|

);
|

}
|

float3 DecodeRGB655ToColor(float2 RGB655)
|

const uint ChannelG = (1 << 5) - 1;
|

const uint ChannelB = (1 << 5) - 1;
|

|

uint2 Inputs = uint2(round(RGB655 * 255.0));
|

uint BitBuffer = (Inputs.x << 8) | Inputs.y;
|

uint R = (BitBuffer & 0xFC00) >> 10;
|

uint G = (BitBuffer & 0x03E0) >> 5;
|

uint B = (BitBuffer & 0x001F);
|
||||
|
||||
return float3(R, G, B) * float3(1.0 / ChannelR, 1.0 / ChannelG, 1.0 / ChannelB);
|

}
|

```

## ShadingModels

### ShadingCommon.ush
|

**添加ShadingModelID宏**：

|
||||
创建了ToonCustomBxDF（**SHADINGMODELID_TOON_BASE**）与ToonLitBxDF（**SHADINGMODELID_TOON_PBR**、**SHADINGMODELID_TOON_SKIN**）2个ShadingModel函数。
|
||||
|
||||
### ToonCustomBxDF的修改
|
||||
Diffuse里面乘以之前在DeferredShadingCommon.ush中计算好的ShadowColor（已经计算了NoL）
|
||||
`Lighting.Diffuse *= AreaLight.FalloffColor * (Falloff * NoL);`
|
||||
=>
|
||||
`Lighting.Diffuse *= AreaLight.FalloffColor * Falloff * GBuffer.ToonCalcShadowColor;`
|
||||
|
||||
Speuclar直接归零，具体是在BasePass阶段进行计算了。
|
||||
`Lighting.Specular = 0；`
|
||||
### ToonLitBxDF的修改
|
||||
Diffuse里面乘以之前在DeferredShadingCommon.ush中计算好的ShadowColor（已经计算了NoL）
|
||||
`Lighting.Diffuse *= AreaLight.FalloffColor * (Falloff * NoL);`
|
||||
=>
|
||||
`Lighting.Diffuse *= AreaLight.FalloffColor * Falloff * GBuffer.ToonCalcShadowColor;`
|
||||
|
||||
Speuclar最后乘以了**Shadow.SurfaceShadow**

||||
`Lighting.Specular *= Shadow.SurfaceShadow;`

## DeferredLightPixelShaders.usf
|
||||
在DeferredLightPixelMain()中添加逻辑:
|
||||
1. 非卡通材质正常渲染。
|
||||
2. 材质材质只有在LightingChannel = 2时才会计算卡通光影效果。
|
||||
```c++
|
||||
bool UseToonShadow = IsToonShadingModel(ScreenSpaceData.GBuffer.ShadingModelID);
|
||||
// LightingChannel Toon Shading only calculate light of LightingChannel = 2
|
||||
BRANCH if (!UseToonShadow || (UseToonShadow && DeferredLightUniforms.LightingChannelMask & 0x4))
|
||||
{
|
||||
const float SceneDepth = CalcSceneDepth(InputParams.ScreenUV);
|
||||
const FDerivedParams DerivedParams = GetDerivedParams(InputParams, SceneDepth);
|
||||
|

|

}
|

#endif
|
||||
|
||||
float Dither = InterleavedGradientNoise(InputParams.PixelPos, View.StateFrameIndexMod8);
|
||||
|

float SurfaceShadow = 1.0f;
|

|

OutColor += Radiance;
|

}
|

```
|

|

# PostProcess
|
||||
## ToneMapping
|
||||
c++部分主要修改了：
|
||||
1. PostProcessing.cpp
|
||||
2. PostProcessTonemap.cpp
|
||||
3. PostProcessTonemap.h
|
||||
|
||||
***实现向ToneMaper Shader传递 `TRDGUniformBufferRef<FSceneTextureUniformParameters>`的功能***
|
||||
|
||||
之后再PostProcessTonemap.usf中，对**CustomStencil**进行判断，如果为true，则直接返回之前渲染结果。实际上BufferVisualization里根本看不出来。
|
||||
```c++
|
||||
#include "DeferredShadingCommon.ush"
|
||||
|
||||
// pixel shader entry point
|
||||
void MainPS(
|
||||
in noperspective float2 UV : TEXCOORD0,
|
||||
in noperspective float2 InVignette : TEXCOORD1,
|
||||
in noperspective float4 GrainUV : TEXCOORD2,
|
||||
in noperspective float2 ScreenPos : TEXCOORD3,
|
||||
in noperspective float2 FullViewUV : TEXCOORD4,
|
||||
float4 SvPosition : SV_POSITION, // after all interpolators
|
||||
out float4 OutColor : SV_Target0
|
||||
#if OUTPUT_LUMINANCE
|
||||
, out float OutLuminance: SV_Target1
|
||||
#endif
|
||||
)
|
||||
{
|
||||
float Luminance;
|

FGBufferData SamplerBuffer = GetGBufferData(UV * View.ResolutionFractionAndInv.x, false);
|
||||
if (SamplerBuffer.CustomStencil > 1.0f && abs(SamplerBuffer.CustomDepth - SamplerBuffer.Depth) < 1)
|
||||
{
|
||||
OutColor = SampleSceneColor(UV);
|
||||
}
|
||||
else
|
||||
{
|
||||
OutColor = TonemapCommonPS(UV, InVignette, GrainUV, ScreenPos, FullViewUV, SvPosition, Luminance);
|
||||
}
|
||||
#if OUTPUT_LUMINANCE
|
||||
OutLuminance = Luminance;
|
||||
#endif
|
||||
}
|
||||
```
|
||||
|
||||
## PostProcessCombineLUT.usf
|
||||
主要移植了UE4版本的LUT，以此保证效果统一。
|
||||
|
||||
# 其他
|
||||
## GpuSkinCacheComputeShader.usf
|
||||
注释2行代码，用处不明。
|
||||
```c++
|
||||
#if GPUSKIN_MORPH_BLEND
|
||||
{
|
||||
Intermediates.UnpackedPosition += Unpacked.DeltaPosition;
|
||||
// calc new normal by offseting it with the delta
|
||||
LocalTangentZ = normalize( LocalTangentZ + Unpacked.DeltaTangentZ);
|
||||
// derive the new tangent by orthonormalizing the new normal against
|
||||
// the base tangent vector (assuming these are normalized)
|
||||
LocalTangentX = normalize( LocalTangentX - (dot(LocalTangentX, LocalTangentZ) * LocalTangentZ) );
|

#if GPUSKIN_APEX_CLOTH

## 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
|
||||
- MI_Brow_V02：
|
||||
- MI_Eye_V02：
|
||||
- MI_EyeGlass_V02：
|
||||
- MI_EyeHighlight_V02：
|
||||
- MI_EyeShadow_V02：
|
||||
- MI_MakeUp_V02：
|
||||
- MI_TeethTongue_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。
|
||||
- MaterialInstance
|
||||
- MI_Outline_V03
|
||||
- MI_Outline_Face_V03
|
||||
- MI_Outline_Hair_V03
|
||||
- MI_Outline_Skin_V03
|
||||
- Dissolve：继承自MaterialInstance文件夹中的对应材质实例，**勾选了EnableDissolve**。
|
||||
# Textures
|
||||
存储一些默认贴图与一些测试用（无用）贴图。
