Name	Type	Remarks	Include Path	Unreal Specifiers
AddSamplesForCollision	bool	If enabled, add extra vertices (without triangles) to the geometry in regions where vertices are spaced too far apart (e.g. across large triangles) These extra vertices will be used as collision samples in particle-implicit collisions, and can help the physics system detect collisions more accurately	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Collision"
Amplitude	float	Size of the Perlin noise displacement (in cm). If 0, no noise will be applied	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Noise" Meta=(DataflowInput, UIMin=0.f)
BoundingBox	FBox		Dataflow/GeometryCollectionFracturingNodes.h	Meta=(DataflowInput, DataflowIntrinsic)
ChanceToFracture	float	Chance to fracture each selected bone. If 0, no bones will fracture; if 1, all bones will fracture.	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Common Fracture" Meta=(DataflowInput, UIMin=0.f, UIMax=1.f)
Collection	FManagedArrayCollection	Collection to fracture	Dataflow/GeometryCollectionFracturingNodes.h	Meta=(DataflowInput, DataflowOutput, DataflowPassthrough="Collection", DataflowIntrinsic)
CollisionSampleSpacing	float	The number of centimeters to allow between vertices on the mesh surface: If there are gaps larger than this, add additional vertices (without triangles) to help support particle-implicit collisions Only used if Add Samples For Collision is enabled	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Collision" Meta=(DataflowInput, UIMin=0.f, EditCondition="AddSamplesForCollision")
Frequency	float	Period of the Perlin noise. Smaller values will create a smoother noise pattern	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Noise" Meta=(DataflowInput, UIMin=0.00001f)
Grout	float	Amount of space to leave between cut pieces	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Common Fracture" Meta=(DataflowInput, UIMin=0.f)
Lacunarity	float	Lacunarity of the layers of Perlin noise.	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Noise" Meta=(DataflowInput, UIMin=0.f)
NewGeometryTransformSelection	FDataflowTransformSelection	Fractured Pieces	Dataflow/GeometryCollectionFracturingNodes.h	Meta=(DataflowOutput, DisplayName="FracturedTransformSelection ")
OctaveNumber	int32	Number of fractal layers of Perlin noise to apply.	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Noise" Meta=(DataflowInput, UIMin=0.f)
Persistence	float	Persistence of the layers of Perlin noise.	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Noise" Meta=(DataflowInput, UIMin=0.f)
PointSpacing	float	Distance (in cm) between vertices on cut surfaces where noise is added.	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Noise" Meta=(DataflowInput, UIMin=0.f)
RandomSeed	int32	Seed for random	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Common Fracture" Meta=(DataflowInput, UIMin="0")
SliceAngleVariation	float	Maximum angle (in degrees) to randomly rotate each slicing plane	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category=Slicing Meta=(DataflowInput, DisplayName="Random Angle Variation", UIMin="0.0", UIMax="90.0")
SliceOffsetVariation	float	Maximum distance (in cm) to randomly shift each slicing plane	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category=Slicing Meta=(DataflowInput, DisplayName="Random Offset Variation", UIMin="0.0")
SlicesX	int32	Number of slices along the X axis	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category=Slicing Meta=(DataflowInput, UIMin="0")
SlicesY	int32	Number of slices along the Y axis	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category=Slicing Meta=(DataflowInput, UIMin="0")
SlicesZ	int32	Number of slices along the Z axis	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category=Slicing Meta=(DataflowInput, UIMin="0")
SplitIslands	bool	Whether to split the fractured mesh pieces based on geometric connectivity after fracturing	Dataflow/GeometryCollectionFracturingNodes.h	EditAnywhere Category="Common Fracture"
TransformSelection	FDataflowTransformSelection	The selected pieces to cut	Dataflow/GeometryCollectionFracturingNodes.h	Meta=(DataflowInput, DataflowOutput, DataflowPassthrough="TransformSelection", DisplayName="TransformSelection")
