hello there, i am having trouble with the VRMLExporter. I am using it e.g. in the Delaunay3D.py example by adding vrml = vtk.vtkVRMLExporter() vrml.SetInput(renWin) vrml.SetFileName("myrenwin.wrl") vrml.Write() after the actors are added at the bottom, but i don't get the right vrml output file. ps how can this be incorporated in paraview? any ideas/answers? axel
