class FCurveSweepOp : public UE::Geometry::FDynamicMeshOperator

Operation for sweeping a profile curve along a sweep curve to create a mesh.

Type	Name	Description
bool	bProfileCurveIsClosed	If true, the last profile curve point will be considered connected to the first.
bool	bSharpNormals	Whether adjacent triangles should share averaged normals or have their own (to give sharpness)
bool	bSweepCurveIsClosed	If true, the last sweep point will be considered connected to the first.
bool	bUVScaleRelativeWorld	If true, UVs are scaled to keep a consistent scale across differently sized geometry.
bool	bUVsSkipFullyWeldedEdges	Whether fully welded edges (welded vertex to welded vertex) in the profile curve should affect the UV layout, since such edges don't generate triangles.
ECapFillMode	CapFillMode	What kind of cap to create.
double	DiagonalTolerance	When QuadSplitMode is ShortestDiagonal, biases one of the diagonals so that symmetric quads are split uniformly.
EProfileSweepPolygonGrouping	PolygonGroupingMode
TArray< FVector3d >	ProfileCurve	Inputs.
TSet< int32 >	ProfileVerticesToWeld
EProfileSweepQuadSplit	QuadSplitMode
double	SharpNormalAngleTolerance	When using sharp normals, the degree difference that adjacent triangles can have in their normals for them to be considered "coplanar" and therefore share normals.
TArray< FFrame3d >	SweepCurve
double	UnitUVInWorldCoordinates	When bUVScaleRelativeWorld is true, the size in world coordinates of 1 UV coordinate.
FVector2d	UVOffset	These values will be added to the generated UV's after applying UVScale.
FVector2d	UVScale	Generated UV's will be multiplied by these values.
