Hi Will,
Yes indeed, we have seen that for VTK Legacy files. What if one has a
vtkPolyData (or any of the other dataset types) and that dataset has a
field array (besides other point or cell arrays)? It does not seem to be a
way to save that dataset as a POLYDATA that includes POINT_DATA, CELL_DATA
and the field data.
