+PS.很有可能在FProjectedShadowInfo::RenderProjection()阶段进行判断以此保证合成正确的**ScreenShadowMask**。
+
+
+# 实现方法
+
+const FMaterialRenderProxy* MaterialRenderProxy = MeshBatch.MaterialRenderProxy;  
+bool bEnableToonMeshDrawOutline = MaterialRenderProxy->GetToonOutlineDataAssetRT()->Settings.bEnableToonMeshDrawOutline;
+
+## 深度偏移
+在FProjectedShadowInfo添加
+RenderDepth()
+
+## DirectionOffsetToViewShadow
+FSceneRenderer::CreateDynamicShadows() -> SetupInteractionShadows()在CreatePerObjectProjectedShadow()添加相关逻辑。
