Quote - obm890, please see my second image and you'll observe multiple narrow faces as you are describing above. In my early morning fatigue I mistakenly referred to this as bevels, They're actually insets.

No, those are the ones I was referring to when I said "Adding a billion polys to your model fixes it but now you have a billion polys in your model." You have 6 very narrow polys going around the corner, those are forming a rounded bevel. Some of those polys turn the corner. The original sharp corner is gone, replaced by those 6 little faces making a rounded edge. They are redundant because Poser can create the illusion of a rounded edge, you just have to control where it happens. 

They are not what I was referring to when I said "all that matters is that there's a narrow poly near the edge in the same plane as the large surface (not bevelled)". In the same plane. The original sharp corner of the object is still there, you just add a control edge very near the corner to limit the extent of the smoothing at render time.

Maybe you started off by insetting the faces in Wings (which is what I'm talking about), but then you hit the subdivide button to get the result you show? 

I'm not saying your solution doesn't work, it does, it's just inefficient. I downloaded your Messiaaahg prop to take a closer look at the modelling and the part you show in the above image is 11700 polys. It's just a stick, perhaps the simplest part of your prop (Antonia-Lo is only 9500 and she's a human figure with eyelashes and fingernails and teeth). The whole Messiaaahg prop is 338000 polys, that's probably a few more than you need to define those forms. If Stonemason made his props with that sort of mesh density his scenes would be unusable.
