Somehow I stopped getting notifications. It's good to see that people are playing with this in Superfly too.

While messing around with an extra, separate EdgeBlend to drive transparency for Superfly I tried using values of PoserSurface transparency higher than 1.0, and since I tried using different values for Transparency and Transparency_Edge I also set Transparency_Falloff non-zero. What surprised me was that when I set both Transparency and Transparency_Edge back to 1.0, Transparency_Falloff still appeared to have a significant effect in Superfly. So I played around a bit more - I ended up with two extra nodes and a Superfly render that more or less matches my Firefly render.

Here's the Superfly version, changes from Firefly version marked in red:

And here's the Firefly one that's in the freebie as a reminder, and for comparison:

And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.
