static uint32 ComputeProjectedSphereScissorRect
(
FIntRect & InOutScissorRect,
FVector SphereOrigin,
float Radius,
FVector ViewOrigin,
const FMatrix & ViewMatrix,
const FMatrix & ProjMatrix
)
Remarks
@parma InOutScissorRect should be set to View.ViewRect before the call 0: light is not visible, 1:use scissor rect, 2: no scissor rect needed
