In paraview, given a vtkMultiBlockDataSet of vtkUnstructedGrid, it is possible to show to which block each vertex or cells belongs by two means. By using vtkBlockColors coloring in the viewports, or in the spreadsheet, there is a column with the block id.
However, for a vtkMultiPieceDataSet of vtkUnstructedGrid, this is not possible. Is there anyway to see to which piece each vertex/cells belongs to?
I have tried with vtkCompositeIndex coloring in the viewport, but apparently the scale is incorrect, my multi piece has 8 pieces and the composite index is going from 8 to 16. Also, it doesn’t work for the spreadsheet view.
