Variables

  Type Name Description  
Public variable UProperty Category, EditAnywhere, Meta bool AutoCluster If true, bones will only be added to the same cluster if they are physically connected (either directly, or via other bones in the same cluster)  
Public variable UProperty Category, EditAnywhere bool AvoidIsolated If true, prevent the creation of clusters with only a single child.  
Public variable UProperty Category, EditAnywhere, Meta bool bPreferConvexity Whether to favor clusters that have a convex shape. (Note: Does not support ByGrid clustering.)  
Public variable UProperty Category, EditAnywhere, Meta float ClusterFraction Choose the number of Voronoi sites used for clustering as a fraction of the number of child bones to process  
Public variable UProperty Category, EditAnywhere, Meta int ClusterGridDepth Choose the number of cluster sites to distribute along the Y axis  
Public variable UProperty Category, EditAnywhere, Meta int ClusterGridHeight Choose the number of cluster sites to distribute along the Z axis  
Public variable UProperty Category, EditAnywhere, Meta int ClusterGridWidth Choose the number of cluster sites to distribute along the X axis  
Public variable UProperty Category, EditAnywhere, Meta DATAFLOW_NODE_DEFINE_INTERNAL(FAutoClusterDataflowNode, "AutoCluster", "GeometryCollection Cluster",... ClusterSites How to choose the size of the clusters to create Use a Voronoi diagram with this many Voronoi sites as a guide for deciding cluster boundaries
Public variable UProperty Meta FManagedArrayCollection Collection Fractured GeometryCollection to cluster  
Public variable UProperty Category, EditAnywhere, Meta float ConcavityTolerance If > 0, cube root of maximum concave volume to add per cluster (ignoring concavity of individual parts)  
Public variable UProperty Category, EditAnywhere, Meta int DriftIterations For a grid distribution, optionally iteratively recenter the grid points to the center of the cluster geometry (technically: applying K-Means iterations) to balance the shape and distribution of the clusters  
Public variable UProperty Category, EditAnywhere, Meta bool EnforceSiteParameters If true, make sure the site parameters are matched as close as possible ( bEnforceConnectivity can make the number of site larger than the requested input may produce without it )  
Public variable UProperty Category, EditAnywhere, Meta float MinimumSize If a cluster has volume less than this value (in cm) cubed, then the auto-cluster process will attempt to merge it into a neighboring cluster.  
Public variable UProperty Category, EditAnywhere, Meta float SiteSize Choose the Edge-Size of the cube used to groups bones under a cluster (in cm).  
Public variable UProperty Meta FDataflowTransformSelection TransformSelection Bone selection for the clustering
