I believe the reader is missing the BlankCells( http://www.vtk.org/doc/nightly/html/classvtkAMRUtilities.html#a6656bada8c6d01b43e15299567af7657) call. If I remember correctly, the blanking cells generated by vtkImageToAMR.cxx get lost when the data is saved to disk (since we don't have a "true" vtkUniformGrid writer, we just write it out as vtkImageData in the vth writer. As a result the blanking arrays need to recomputed on reading back in.
Mind reporting a bug for this? Thanks.
