quickly illuminate an object where the shading has made the colors murky. Is there a compelling reason to get rid of it? It’s tucked away in an innocuous corner of the GUI.<u></u><u></u></span></p>

<a href="http://www.vtk.org/doc/release/5.0/html/a01682.html" target="_blank">vtkLightKit</a>. You can however add an extra headlight. I am about to add a more general capability which lets you add any number and any kind of light, including the headlight. When I do that,
the semi-hardcoded extra headlight becomes redundant. I would like to remove it to streamline both the code and the UI.<u></u><u></u></p>
