It is this line: 133 sgrid->SetDimensions(count[0], count[1], count[2]); This is equivalent to sgrid->SetExtent(0, count[0]-1, 0, count[1]-1, 0, count[2]-1); which overwrites the earlier SetExtent() call. If you get rid of it, it should work fine.

I've included a plugin that demonstrates the problem - a little "importer" that hardwires a whole extent of 0,10 in each axis. In RequestInformation it calls: outInfo->Set(vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(),this->Internals->extent,6); outInfo->Set(CAN_PRODUCE_SUB_EXTENT(), 1); and in RequestData it calls outInfo->Get(vtkStreamingDemandDrivenPipeline::UPDATE_EXTENT(),subext); vtkStructuredGrid *sgrid = vtkStructuredGrid::SafeDownCast(output); sgrid->SetExtent(subext); to get the update extent from the pipeline and set it onto the structured grid.. It then stuffs points and data to create a grid from -1 to 1 in each axis. When I run it on 2 processes, the result *looks* right, it fills the -1 to 1 space along each axis, there are the right number of cells and points, ProcessIdScalars shows two equal size partitions, but the extent is clearly not right - the wireframe and surface surface boundaries are incomplete and the extent shown in the Information tab is correct for only one of the two parts. So, what am I doing wrong? If anyone is interested, I uploaded the plugin code to: https://utexas.box.com/s/d6ef5kx4oxm1d205hbbo Gregory D.
