<a href="https://gitlab.kitware.com/paraview/paraview/issues/17236">https://gitlab.kitware.com/paraview/paraview/issues/17236</a>. Until that bug is fixed, I would argue strenuously against disabling the headlight. The implementation of the bug fix may or may
not require the headlight to stick around (depending on how it is implemented).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">I don’t personally have any other use case for the headlight, but it is a convenient way to get a bright light shining directly on the view. It’s valuable to
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.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">No objection here. Only thought I have is that the lights may be setup by default slightly differently for 2d and 3d. We may want a “headlight” for 2d.<o:p></o:p></span></p>

<a href="http://www.vtk.org/doc/release/5.0/html/a01682.html">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.<o:p></o:p></p>
