I applaud your desire and effort to share.
However - I feel you should know that your basic gold metal (left) isn't at all close to realistic. Your color ratios should be at or near RGB 255, 215, 150 (middle is your shader with that value). However, it is my opinion that the Poser 11 Physical Surface isn't quite correct yet and should be used with some caution at this time, although the errors I've found in it are really small. On the right is my own shader for gold that I made from Cycles GlossyBsdf and a FresnelBlend, using the same RGB 255, 215, 150, but blending to white at the outer edges. The PhysicalSurface is blending to pink, which is incorrect - not physically correct at all. I'm going to do more experiments and have a talk with SM about it.
Also, your FireFly versions are using Diffuse - basic polished metal has 0 or near 0 diffuse, so you should be setting Diffuse_Value = 0 for the FF versions of metals.
In fact, if you had just used the colored Reflect in FF and SF you'd get the same shader working fine in both. Note, however, that SuperFly roughness numbers don't match those in FireFly - so the same shader works, but the same parametric values do not. Such a shame.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
