Bug in vtkVRMLExporter ?

[Paul Hsieh]

You can turn the headlights on the VRML file as follows.
Before you export the VRML file, remove all the lights in
your renderer. This will force vtkVRMLExporter to add a headlight. 
(See the WriteData() method of vtkVRMLExporter.) Then after
your have exported your VRML file, you can turn the lights
back on.
