Functions

  Type Name Description
Public function Virtual Const FVector

GetPerObjectProjectedShadowProjectionPoint ( const FBoxSphereBounds& SubjectBounds
)

  
Protected function void

UpdateRadius ( float ComponentRadius
)

 Updates the light scene info's radius from the component.
Public function void

UpdateRadius_GameThread ( float Radius
)

 Called on the light scene info after it has been passed to the rendering thread to update the rendering thread's cached info when the light's radius changes.
