Name	Type	Remarks	Include Path	Unreal Specifiers
bOnlyConnectedToHull	bool	When protecting negative space, only look for space that is connected out to the convex hull.	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=NegativeSpace Meta=(DataflowInput, EditCondition="bProtectNegativeSpace")
bProtectNegativeSpace	bool	Whether to drive decomposition by finding a negative space that should not be covered by convex hulls.	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=NegativeSpace Meta=(DataflowInput)
DecompositionSettings	FDataflowConvexDecompositionSettings		Dataflow/GeometryCollectionUtilityNodes.h	Meta=(DataflowOutput)
ErrorTolerance	float	Stop splitting when hulls have error less than this (expressed in cm; will be cubed for volumetric error).	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=Decomposition Meta=(ClampMin=0.0, Units=cm, DataflowInput, EditCondition="!bProtectNegativeSpace")
MaxGeoToHullVolumeRatioToDecompose	DATAFLOW_NODE_DEFINE_INTERNAL(FMakeDataflowConvexDecompositionSettingsNode, "MakeConvexDecompositionSettings", "GeometryCollection	Utilities", "") public float	If the geo volume / hull volume ratio is greater than this, do not consider convex decomposition.	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=Filter Meta=(ClampMin=0.0, ClampMax=1.0, DataflowInput)
MaxHullsPerGeometry	int32	If greater than zero, maximum number of convex hulls to use in each convex decomposition.	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=Decomposition Meta=(ClampMin=1, DataflowInput)
MinThicknessTolerance	float	Optionally specify a minimum thickness (in cm) for convex parts; parts below this thickness will always be merged away. Overrides NumOutputHulls and ErrorTolerance when needed.	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=Decomposition Meta=(ClampMin=0.0, DataflowInput)
NegativeSpaceMinRadius	float	Spheres smaller than this are not included in the negative space	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=NegativeSpace Meta=(DataflowInput, ClampMin=0, Units=cm, EditCondition="bProtectNegativeSpace")
NegativeSpaceTolerance	float	Amount of space to leave between convex hulls and protected negative space	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=NegativeSpace Meta=(DataflowInput, ClampMin=.01, UIMin=.1, Units=cm, EditCondition="bProtectNegativeSpace")
NumAdditionalSplits	int32	Control the search effort spent per convex decomposition: larger values will require more computation but may find better convex decompositions.	Dataflow/GeometryCollectionUtilityNodes.h	EditAnywhere Category=Decomposition Meta=(ClampMin=0, DataflowInput, EditCondition="!bProtectNegativeSpace")
