+# Toon Lumen
+抹平法线思路：
+
+在`LumenScreenProbeGather.usf`中对法线进行抹平处理。其Pass位于
+- DiffuseIndirectAndAO
+ - LumenScreenProbeGather
+ - Integrate
+ - SimpleDiffuse/SupportImportanceSampleBRDF?/SupportAll?
+
+在如下位置添加代码：
+```c++
+if (IsValid(Material))
+ {
+ const float2 ScreenUV = (Coord.SvPosition + 0.5f) * View.BufferSizeAndInvSize.zw;
+ const float3 WorldPosition = GetWorldPositionFromScreenUV(ScreenUV, Material.SceneDepth);
+ const float3 WorldNormal = Material.WorldNormal;
+ //BlueRose Modify
+ if (Material.ShadingID == SHADINGMODELID_TOONSTANDARD)
+ {
+ //使用Yu-ki016的方法“抹平法线”
+ float3 V = normalize(LWCHackToFloat(PrimaryView.WorldCameraOrigin) - WorldPosition);
+ const uint ToonDataAssetID = GetToonDataAssetIDFromGBuffer(Material.GBufferData);
+ float DiffuseIndirectLightingFlatten = GetDiffuseIndirectLightingFlatten(ToonDataAssetID);
+ Material.WorldNormal = normalize(lerp(WorldNormal, V, DiffuseIndirectLightingFlatten));
+ }
+ //BlueRose Modify End
+ ...
+ }
+}
+```
+
+该方法存在一些问题：**当相机围绕角色旋转时，角色身上的 GI变化会比较明显**。
+
+# Spherical Harmonics
+UE5中采样球谐贴图方法(ReflectionEnvironmentShared.ush)：
+```c++
+/**
+ * Computes sky diffuse lighting from the SH irradiance map.
+ * This has the SH basis evaluation and diffuse convolution weights combined for minimal ALU's - see "Stupid Spherical Harmonics (SH) Tricks"
+ */
+float3 GetSkySHDiffuse(float3 Normal)
+{
+ float4 NormalVector = float4(Normal, 1.0f);
+
+ float3 Intermediate0, Intermediate1, Intermediate2;
+ Intermediate0.x = dot(SkyIrradianceEnvironmentMap[0], NormalVector);
+ Intermediate0.y = dot(SkyIrradianceEnvironmentMap[1], NormalVector);
+ Intermediate0.z = dot(SkyIrradianceEnvironmentMap[2], NormalVector);
+
+ float4 vB = NormalVector.xyzz * NormalVector.yzzx;
+ Intermediate1.x = dot(SkyIrradianceEnvironmentMap[3], vB);
+ Intermediate1.y = dot(SkyIrradianceEnvironmentMap[4], vB);
+ Intermediate1.z = dot(SkyIrradianceEnvironmentMap[5], vB);
+
+ float vC = NormalVector.x * NormalVector.x - NormalVector.y * NormalVector.y;
+ Intermediate2 = SkyIrradianceEnvironmentMap[6].xyz * vC;
+
+ // max to not get negative colors
+ return max(0, Intermediate0 + Intermediate1 + Intermediate2);
+}
+```
