Is it possible to get some guidance about how the distributed data will work w.r.t. duplicated trees between difference pieces? For example could one tree (e.g. ID 0) in one piece have descriptors like 1 0 0 0 1 where another piece has descriptors for the same tree (also ID 0) like 1 1 0 0 0 and if so how VTK interprets this? Or is is strictly necessary that the pieces are disjoint sets of trees?
