Clip observers MUST derive from <a class="el" href="class_NL3D__IBaseLightObs.html">IBaseLightObs</a>. This observer:<ul>
<li>leave the notification system to DO NOTHING.<li>implement the <a class="el" href="class_NL3D__CDefaultLightObs.html#a0">traverse</a>() method to DO NOTHING (but <a class="el" href="class_NL3D__IObs.html#a16">traverseSons</a>()).</ul>
