# 前言
|
||||
截止版本UE5.3.2。添加了一种新的GBuffer精度格式GBT_Uint_32_32_32_32，以及RT7。
|
||||
|
||||
修改内容：
|
||||
- GBufferPostDecode.ush：在GBufferPostDecode中给FGBufferData添加InitMooaToonContext()逻辑
|
||||
- SceneRendering.cpp：Debug用的渲染变量调节，并且在FViewInfo::SetupUniformBufferParameters()添加设置相关变量的逻辑。
|
||||
- 其他：
|
||||
- MaterialBaking：ExportMaterialProxy.h
|
||||
- MaterialEditor：MaterialEditor.cpp
|
||||
- PixelInspector：PixelInspectorResult.cpp、PixelInspectorResult.h
|
||||
|
||||
# ToonShadingCommon.ush
|
||||
除了一下工具函数，主要实现：
|
||||
1. GBuffer的一些Encode / Decode Helper函数。
|
||||
2. 用于存储数据的struct FMooaToonData、FMooaToonContext。
|
||||
3. 针对上面2个结构体编码与解码的函数。FMooaCustomPayload用于光追Shader。
|
||||
|
||||
## 数据结构体
|
||||
```c++
|
||||
struct FMooaToonContext
|
||||
{
|
||||
FMooaToonData MooaToonData;
|
||||
bool IsMainLight;
|
||||
float3 LightColor;
|
||||
bool IsEditorPreviewWorldType;
|
||||
float Exposure;
|
||||
uint2 PixelPos; // SVPos.xy
|
||||
};
|
||||
|
||||
struct FMooaToonData
|
||||
{
|
||||
// Diffuse
|
||||
float3 MainLightShadowColor;
|
||||
float MainLightShadowValueOffset;
|
||||
float MainLightShadowApplyLightColor;
|
||||
float OtherLightDiffuseThreshold;
|
||||
float OtherLightDiffuseFeather;
|
||||
float GlobalIlluminationIntensity;
|
||||
float GlobalIlluminationDirectionality;
|
||||
|
||||
// Specular
|
||||
float3 SpecularColor;
|
||||
float SpecularThreshold;
|
||||
float SpecularFeather;
|
||||
float ReflectionIntensity;
|
||||
bool IsPBRSpecular;
|
||||
float RimLightIntensity;
|
||||
float RimLightWidth;
|
||||
float RimLightAngle;
|
||||
float RimLightDepthThreshold;
|
||||
// Ray Tracing Shadow
|
||||
uint Stencil;
|
||||
uint RayTracingShadowFlag;
|
||||
float HairShadowWidth;
|
||||
float HairShadowIntensity;
|
||||
|
||||
// Unused
|
||||
float CustomData3;
|
||||
};
|
||||
```
|
||||
## Encode/Decode
|
||||
这里推荐使用计算器进行计算更加好理解。
|
||||
```c++
|
||||
//取得指定Bits位数的最大数值，8位 => 255
|
||||
uint GetBitsMaxValue(int Bits = 8) {return (1L << Bits) - 1;}
|
||||
|
||||
//将2个uint合并1个uint，将Src1移动Scr2的位数后，将2者进行或运算合并到一起。
|
||||
uint EncodeUint2ToUint(uint Src1, uint Src2, int BitsSrc1 = 8, int BitsSrc2 = 8)
|
||||
{
|
||||
return ((Src1 & GetBitsMaxValue(BitsSrc1)) << BitsSrc2) |
|
||||
(Src2 & GetBitsMaxValue(BitsSrc2));
|
||||
}
|
||||
|
||||
//将2个uint合并1个uint后转换成浮点数（0~1）
|
||||
float EncodeUint2ToFloat(uint Src1, uint Src2, int BitsSrc1 = 8, int BitsSrc2 = 8)
|
||||
{
|
||||
return float(EncodeUint2ToUint(Src1, Src2, BitsSrc1, BitsSrc2)) / GetBitsMaxValue(BitsSrc1 + BitsSrc2);
|
||||
}
|
||||
|
||||
//将合并后Uint还原成2个uint
|
||||
void DecodeUint2FromUint(uint Src, out uint Dst1, out uint Dst2, int BitsDst1 = 8, int BitsDst2 = 8)
|

|
||||
{
|

uint FloatToUint = uint(Src * GetBitsMaxValue(BitsDst1 + BitsDst2));
|
||||

|

}

|
||||
}
|
||||
|
||||
//将uint还原成float（0~1）
|
||||
float DecodeFloatFromUint(uint Src, int BitsDst1 = 8)
|
||||
{
|
||||

|
||||
}
|
||||
|
||||
void DecodeFloat2FromUint(uint Src, out float Dst1, out float Dst2, int BitsDst1 = 8, int BitsDst2 = 8)
|
||||

|
||||

|
||||

|

|
||||

|
||||
}
|
||||
|
||||
void DecodeFloat2FromFloat(float Src, out float Dst1, out float Dst2, int BitsDst1 = 8, int BitsDst2 = 8)
|
||||
{
|
||||
uint OutUint1, OutUint2;
|
||||
DecodeUint2FromFloat(Src, OutUint1, OutUint2, BitsDst1, BitsDst2);
