However, containerFields with Texture trailing the side do not.

5. <u style="font-family:monospace" class=""><b style="font-family:monospace" class="">How do I implement chromatic aberration in X3D?</b></u> (See PlayCanvas in flowers.xhtml above). Preferably, not dropping into a shading language, so I can use an enduring standard.
