Public function Const FTransform Returns the transform for transforming from bone space to collection space for specified bone Vertex(inCollectionSpace) = TransformComputed.TransformPosition(Vertex(inBoneSpace))
Public function Const TArray< FTransform > Returns array of transforms for transforming from bone space to collection space Vertex(inCollectionSpace) = TransformComputed.TransformPosition(Vertex(inBoneSpace))
Public function void Creates the facade attributes.
Public function Const const TManagedArray< TSet< int32 > > * Returns the child indicesfrom the collection. Null if not initialized.
Public function Const const TManagedArray< FTransform > * Returns the child indicesfrom the collection. Null if not initialized.
Public function Const const TManagedArray< int32 > * Returns the parent indices from the collection. Null if not initialized.
