<div dir="ltr"><div>Bob,<br><br>There is no control for that just yet. Work is in progress to provide the full complement of light controls. If you are working in builting mode, you can resort to python as follows.<br><br></div><div>lights = GetActiveView().GetRenderer().GetLights()<br></div>for i in range(0, lights.GetNumberOfItems()):<br><div> lights.GetItemAsObject(i).SetLightTypeToSceneLight()<br></div><div><br>Note: the light position bug in 5.1 that Alan was referring to had the effect of making making the light positions fixed (scene lights in vtk terms). In 5.2 that was corrected and now they are camera relative lights that move with the viewer as they do with GL rendering.<br><br></div><div>hope that helps<br></div><br><div><br><br><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature">David E DeMarle<br>Kitware, Inc.<br>R&D Engineer<br>21 Corporate Drive<br>Clifton Park, NY 12065-8662<br>Phone: 518-881-4909</div></div>

As I move the model around in 3d with the mouse, I'd like the shadow to remain perpendicular to the arrows, similar to how it would look if I walked around the cylinder on a sunny day (assuming I didn't walk extremely slowly). I'd like the light source to be fixed relative to ground rather than the screen - I'm surprised that isn't the default or an option (at least I haven't found it).<br><br></div>Thanks, Bob <br><br></div>ParaView 5.2 on Windows 7<br></div><div class="gmail_extra"><br><div class="gmail_quote"><span class="">On 6 January 2017 at 00:17, Scott, W Alan <span dir="ltr"><<a href="mailto:wascott@sandia.gov" target="_blank">wascott@sandia.gov</a>></span> wrote:<br></span><div><div class="h5"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
