Hi Stefan, It turns out that MITK always, regardless of the selected file ending, picks the mitk::UnstructuredGridVtkWriter<vtkXMLPUnstructuredGridWriter> to save unstructured grids. In practice this means it writes a composition vtu (usually .pvtu) with the wrong file ending (whichever the user selected).
The file reader on the other hand seems to trust the fileending and thus fails to notice that the .vtu being loaded is actually a .pvtu and simply doesn’t load the referenced sub pieces. But i didn’t really look into this as i didn’t need the ability to read pvtu. For my current use case i just disabled the vtkXMLPUnstructuredGridWriter in mitkIOExtObjectFactory.cpp as i don’t need the support for it.
