static int32 bspBrushCSG ( ABrush* Actor, UModel* Model, UModel* TempModel, UMaterialInterface* SelectedMaterialInstance, uint32 PolyFlags, EBrushType BrushType, ECsgOper CSGOper, bool bBuildBounds, bool bMergePolys, bool bReplaceNULLMaterialRefs, bool bShowProgressBar )	Performs any CSG operation between the brush and the world.	BSPUtils.h
static void bspBuildFPolys ( UModel* Model, bool SurfLinks, int32 iNode, TArray< FPoly >* DestArray )	Build EdPoly list from a model's Bsp. Not transactional.	BSPUtils.h
static void bspCleanup ( UModel* Model )	Clean up all nodes after a CSG operation.	BSPUtils.h
static void bspMergeCoplanars ( UModel* Model, bool RemapLinks, bool MergeDisparateTextures )		BSPUtils.h
static int32 bspNodeToFPoly ( UModel* Model, int32 iNode, FPoly* EdPoly )	Convert a Bsp node to an EdPoly. Returns number of vertices in Bsp node.	BSPUtils.h
static void bspOptGeom ( UModel* Model )	Optimize a level's Bsp, eliminating T-joints where possible, and building side links.	BSPUtils.h
static void bspRepartition ( UWorld* InWorld, int32 iNode )	Repartition Bsp tree	BSPUtils.h
static bool polyFindBrush ( UModel* InModel, int32 iSurf, FPoly& Poly )	Find the Brush EdPoly corresponding to a given Bsp surface.returns true if poly not available	BSPUtils.h
static bool polyFindMaster ( UModel* InModel, int32 iSurf, FPoly& Poly )		BSPUtils.h
static void polyGetLinkedPolys ( ABrush* InBrush, FPoly* InPoly, TArray< FPoly >* InPolyList )	Populates a list with all polys that are linked to the specified poly.	BSPUtils.h
static 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).	BSPUtils.h
static void polySetAndClearPolyFlags ( UModel* Model, uint32 SetBits, uint32 ClearBits, bool SelectedOnly, bool UpdateBrush )	Sets and clears all Bsp node flags. Affects all nodes, even ones that don't really exist.	BSPUtils.h
static 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.	BSPUtils.h
static void polyUpdateBrush ( UModel* Model, int32 iSurf, bool bUpdateTexCoords, bool bOnlyRefreshSurfaceMaterials )	Update the brush EdPoly corresponding to a newly-changed poly to reflect its new properties.	BSPUtils.h
static void polyUpdateMaster ( UModel* Model, int32 iSurf, bool bUpdateTexCoords, bool bOnlyRefreshSurfaceMaterials )		BSPUtils.h
