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];
}
