<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D"> Sorry for the noise. It looks like you actually have to have an actor that *<b>is</b>* transparent included in the renderer for depth peeling to be used, even if you’ve requested
it to be activated. Looks like I was bumping up against an somewhat obvious optimization. Once I included an actor that was not fully opaque the rendering code reported that depth peeling was activated.</span></p>
