Syntax

Chaos::TPBDRigidClusteredParticleHandle< float, 3 > * BuildClusters
(
    const uint32 CollectionClusterIndex,
    TArray< Chaos::TPBDRigidParticleHandle< float, 3 > * > & ChildHandles,
    const TArray< int32 > & ChildTransformGroupIndices,
    const Chaos::FClusterCreationParameters & Parameters,
    const Chaos::FUniqueIdx * ExistingIndex
)

Remarks

Build a physics thread cluster parent particle. CollectionClusterIndex_ - the source geometry collection transform index. ChildHandles - physics particle handles of the cluster children. `ChildTransformGroupIndices - geometry collection indices of the children. Parameters - uh, yeah... Other parameters.
