GetFirstWholeSceneShadowMap()

const FProjectedShadowInfo * GetFirstWholeSceneShadowMap

(

const FVisibleLightInfo &

VisibleLightInfo

)

Fetch the first allocated whole scene shadow map for a given light. Since shadows maps for directional lights are sorted far cascades -> near cascades, this will grab the furthest cascade, which is the typical use case.
