struct PAPER2FSpriteGeometryCollection

Type	Name	Description
float	AlphaThreshold	Alpha threshold for a transparent pixel (range 0..1, anything equal or below this value will be considered unimportant)
bool	bAvoidVertexMerging	Experimental: Hint to the triangulation routine that extra vertices should be preserved.
float	DetailAmount	Amount to detail to consider when shrink-wrapping (range 0..1, 0 = low detail, 1 = high detail)
TEnumAsByte< ESpritePolygonMode::Type >	GeometryType	The geometry type (automatic / manual)
int32	PixelsPerSubdivisionX	Size of a single subdivision (in pixels) in X (for Diced mode)
int32	PixelsPerSubdivisionY	Size of a single subdivision (in pixels) in Y (for Diced mode)
TArray< FSpriteGeometryShape >	Shapes	List of shapes.
float	SimplifyEpsilon	This is the threshold below which multiple vertices will be merged together when doing shrink-wrapping. Higher values result in fewer vertices.

Type	Name	Description
void	AddCircleShape ( FVector2D Position, FVector2D Size )
void	AddRectangleShape ( FVector2D Position, FVector2D Size )
bool	ConditionGeometry ()	Conditions this geometry collection (turning Polygons back to Boxes if they meet the definition of a box, etc...) Returns true if something was modified
	FSpriteGeometryCollection ()
void	Reset ()	Empties this geometry collection, resetting the GeometryType to TightBoundingBox.
void	Triangulate ( TArray< FVector2D >& Target, bool bIncludeBoxes )	Takes all polygon shapes and generates a list of triangles from them.
