I am unfamiliar with the AMR datasets/file types but if you decide to create your own reader, it isn’t all that difficult using ParaView 5.6’s new [Python Algorithm plugin capability](https://gitlab.kitware.com/paraview/paraview/blob/master/Examples/Plugins/PythonAlgorithm/PythonAlgorithmExamples.py).

Check out [this post](https://discourse.paraview.org/t/how-to-get-block-indexes-in-python/797/2) and [this snippet](https://github.com/OpenGeoVis/PVGeo/blob/master/snippets/PV_Composite_Writer.py) from [**PVGeo**](http://pvgeo.org) for details on making your own file writers!
