Try using a conditional expression in the calculator to set the invalid values to some slightly off range value. Then edit the color map to make that off range value completely transparent.<br><br>David E DeMarle<br>Kitware, Inc.<br>

I used a vtkProbeFilter to resample an unstructured grid dataset onto a vtkStructuredPoints, which I then tried to volume render in Paraview. The result is attached. Paraview seems to be ignoring the vtkValidPointMask and instead rendering every point whether it is valid or not. Is there some way to get Paraview to exclude invalid points from the volume rendering?<br>
