Rendering fields defined in some blocks of a multiblock

Hello all,

I’ve not thoroughly looked at how to render vtkMultiblockDataSets, I’ve noticed that there are a vtkCompositePolyDataMapper and vtkCompositePolyDataMapper2 (the latter seem to be deprecated).
For the setup of the pipeline, I’m using:

vtkAMultiblockReader → vtkGeometryFilter → vtkCompositeDataMapper → vtkActor

At that point I want to display a field whose values correspond only to block[1] (let’s say these are partial data).

Could you please suggest a more appropriate way of displaying partial data?
Does the setup of the pipeline for my use case seem reasonable?

Let me know what you think and many thanks!!
