<p class="MsoNormal">Dave Karelitz was showing me the can in ParaView, and I wonder if our lights model is incorrect. Here is how to replicate:<o:p></o:p></p>

<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Open can.exo. Apply. Last frame. Color by Solid Color. Reset.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Now, rotate the can.

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What you will notice is that the lights are not attached to the scene (i.e., stationary), but attached to the camera (i.e., moving). This is really obvious if you turn on OSPRay and shadows.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Isn’t this wrong? The data should remain stationary, the lights (other than a headlight) should stay stationary, and the camera should move around the scene?<o:p></o:p></p>
