class FStaticMeshStaticLightingMesh : public FStaticLightingMesh

Represents the triangles of one LOD of a static mesh primitive to the static lighting system.

	Type	Name	Description
	const int32	LODIndex	The LOD this mesh represents.
	TArray< FStaticLightingMesh * >	OtherLODs	The meshes representing other LODs of this primitive.

	Type	Name	Description
		FStaticMeshStaticLightingMesh ()
		FStaticMeshStaticLightingMesh ( const UStaticMeshComponent* InPrimitive, int32 InLODIndex, const TArray< ULightComponent* >& InRelevantLights )	Initialization constructor.

	Type	Name	Description
	const FSplineMeshParams *	GetSplineParameters ()
	void	SetLocalToWorld ( const FMatrix& InLocalToWorld )	Sets the local to world matrix for this mesh, will also update LocalToWorldInverseTranspose

Type	Name	Description
void	ExportMeshInstance ( FLightmassExporter* Exporter )	Export static lighting mesh instance data to an exporter
void	GetTriangle ( int32 TriangleIndex, FStaticLightingVertex& OutV0, FStaticLightingVertex& OutV1, FStaticLightingVertex& OutV2 )	Accesses a triangle.
void	GetTriangleIndices ( int32 TriangleIndex, int32& OutI0, int32& OutI1, int32& OutI2 )	Accesses a triangle's vertex indices.
FLightRayIntersection	IntersectLightRay ( const FVector& Start, const FVector& End, bool bFindNearestIntersection )	Checks if a line segment intersects the mesh.
bool	IsControllingShadowPerElement ()
bool	IsInstancedMesh ()	Returns true if this mesh is an instanced mesh.
bool	IsTriangleCastingShadow ( uint32 TriangleIndex )
bool	IsUniformShadowCaster ()	Checks whether ShouldCastShadow will return true always.
bool	ShouldCastShadow ( ULightComponent* Light, const FStaticLightingMapping* Receiver )	Determines whether the mesh should cast a shadow from a specific light on a specific mapping.
