[vtkusers] lighting question

[David Bourg]

Hello,

I'm setting up a simple scene (my first) and have encountered a little
problem.  I've added a single light to my scene to act as a key light but
the result didn't look right.  It appears as though there is some other
light also in the scene and this one seems to move around with my camera.
Further, if I set the intensity of my key light to zero, the scene is still
illuminated by that other light. How do I get rid of it?

Thanks,

David
