Functions

		Name	Description
	int32	bspBrushCSG ( ABrush* Actor, UModel* Model, UModel* TempModel, UMaterialInterface* SelectedMa..., uint32 PolyFlags, EBrushType BrushType, ECsgOper CSGOper, bool bBuildBounds, bool bMergePolys, bool bReplaceNULLMaterialRefs, bool bShowProgressBar )	Performs any CSG operation between the brush and the world.
	void	bspBuildFPolys ( UModel* Model, bool SurfLinks, int32 iNode, TArray< FPoly >* DestArray )	Build EdPoly list from a model's Bsp. Not transactional.
	void	bspCleanup ( UModel* Model )	Clean up all nodes after a CSG operation.
	void	bspMergeCoplanars ( UModel* Model, bool RemapLinks, bool MergeDisparateTextures )
	int32	bspNodeToFPoly ( UModel* Model, int32 iNode, FPoly* EdPoly )	Convert a Bsp node to an EdPoly. Returns number of vertices in Bsp node.
	void	bspOptGeom ( UModel* Model )	Optimize a level's Bsp, eliminating T-joints where possible, and building side links.
	void	bspRepartition ( UWorld* InWorld, int32 iNode )	Repartition Bsp tree
	bool	polyFindMaster ( UModel* InModel, int32 iSurf, FPoly& Poly )	Find the Brush EdPoly corresponding to a given Bsp surface. returns true if poly not available
	void	polyGetLinkedPolys ( ABrush* InBrush, FPoly* InPoly, TArray< FPoly >* InPolyList )	Populates a list with all polys that are linked to the specified poly.
	void	polyGetOuterEdgeList ( TArray< FPoly >* InPolyList, TArray< FEdge >* InEdgeList )	Takes a list of polygons and returns a list of the outside edges (edges which are not shared by other polys in the list).
	void	polySetAndClearPolyFlags ( UModel* Model, uint32 SetBits, uint32 ClearBits, bool SelectedOnly, bool UpdateMaster )	Sets and clears all Bsp node flags. Affects all nodes, even ones that don't really exist.
	void	polySplitOverlappingEdges ( TArray< FPoly >* InPolyList, TArray< FPoly >* InResult )	Takes a list of polygons and creates a new list of polys which have no overlapping edges.
	void	polyUpdateMaster ( UModel* Model, int32 iSurf, bool bUpdateTexCoords, bool bOnlyRefreshSurfaceMaterials )	Update a the master brush EdPoly corresponding to a newly-changed poly to reflect its new properties.
