<u></u><u></u></li></ul>
<p class="MsoNormal"><u></u> <u></u></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.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></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?<u></u><u></u></p>
