I was able to get it working again by :<br>1) Adding the blanking array to the dataset as a PointData Array, as well as the "Blanking" array. This got the cross-sections working.<br>2) Switching from vtkDAtaSetSurfaceFilter to vtkSTructuredGridGeometryFilter, which gets the surface extraction working. <br>

Have you looked for a bug? It could be under VTK or ParaView. In ParaView 2.6.1 I think the bug was in vtkDataSetSurfaceFilter.cxx.<br>

I'm building a vtkStructuredGrid with a single array in it (Temperature), and using the "Mask" value (4095) to set the blanking property. It doesn't seem to do anything tho? Once I've built the dataset, cross sections and surface extractions both show all the 4095 values. Is there some trick to getting this to work?<br>
