# 关键函数
|
||
|
|
取得所有ShadowMap的投影信息
|
||
|
|
```c++
|
||
|
|
const FVisibleLightInfo& VisibleLightInfo = VisibleLightInfos[LightSceneInfo->Id];
|
||
|
|
const TArray<FProjectedShadowInfo*, SceneRenderingAllocator>& ShadowMaps = VisibleLightInfo.ShadowsToProject;
|
||
|
|
for (int32 ShadowIndex = 0; ShadowIndex < ShadowMaps.Num(); ShadowIndex++)
|
||
|
|
{
|
||
|
|
const FProjectedShadowInfo* ProjectedShadowInfo = ShadowMaps[ShadowIndex];
|
||
|
|
}
|
||
|
|
```

## InjectSimpleTranslucencyLightingVolumeArray
|
||
|
|
插入简单透明体积物体渲染。应该是根据3D贴图渲染体积效果。默认状态下不运行。
