Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere, Meta bool bComputeNegativeSpacePerBone Whether to compute separate negative space for each bone.
Public variable UProperty Category, EditAnywhere, Meta bool bOnlyConnectedToHull When performing Voxel Search, only look for negative space that is connected out to the convex hull.
Public variable UProperty Category, EditAnywhere, Meta bool bProtectNegativeSpace Whether to use a sphere cover to define negative space that should not be covered by convex hulls
Public variable UProperty Category, EditAnywhere, Meta bool bRequireSearchSampleCoverage Whether to require that all candidate locations identified by Voxel Search are covered by negative space samples, up to the specified Min Sample Spacing.
Public variable UProperty Category, EditAnywhere, Meta double ErrorTolerance Error tolerance to use to decide to merge leaf convex together.
Public variable UProperty Category, EditAnywhere, Meta int32 MaxConvexCount Maximum number of convex to generate per transform. Ignored if < 0.
Public variable UProperty Category, EditAnywhere, Meta double MinRadius Spheres smaller than this are not included in the negative space
Public variable UProperty Category, EditAnywhere, Meta double MinSampleSpacing Minimum desired spacing between spheres; if > 0, will attempt not to place sphere centers closer than this
Public variable UProperty Category, EditAnywhere, Meta double NegativeSpaceTolerance Amount of space to leave between convex hulls and protected negative space
Public variable UProperty Meta FDataflowTransformSelection OptionalSelectionFilter Optional transform selection to compute cluster hulls on if not provided, all cluster hulls will be computed.
Public variable UProperty Category, EditAnywhere, Meta ENegativeSpaceSampleMethodDataflowEnum SampleMethod Method to use to find and sample negative space
Public variable UProperty Meta DATAFLOW_NODE_DEFINE_INTERNAL(FMergeConvexHullsDataflowNode, "MergeConvexHulls", "GeometryCollection... SphereCovering A representation of the negative space protected by the 'protect negative space' option. If negative space is not protected, this will contain zero spheres.
Public variable UProperty Category, EditAnywhere, Meta int32 TargetNumSamples Approximate number of spheres to consider when covering negative space
