Ironsoul's comment about displacement over on the PBR thread reminded me that Superfly doesn't do micropolygon displacement, so I need to make a slight addition to item 9 in my previous summary.

....

So connecting PBR maps to a Poser Physical Surface node is mostly very obvious (1-5, 9), with a couple of _"Ah, I thought so!"_s (8, 6) , but one googly (7)

1. Transparency Map (greyscale) => Transparency I/P (numeric)
2. Normal Map (colour) => NormalMap I/P (numeric)
3. Emission Map (greyscale) => Emission I/P (colour)
4. Metallic Map (greyscale) => Metallic I/P (numeric)
5. Roughness Map (greyscale) => Roughness I/P (numeric)
6. Gloss (greyscale) => Invert => Roughness I/P (numeric)
7. Specular (greyscale) => Multiply by 12.5 ?! => Specular I/P (colour)
8. Albedo Map (colour) => Color I/P (colour)
9. Height Map (greyscale) => Displacement (numeric) ...N.B. Superfly does NOT support micropolygon displacement, so the resolution of the displacement is down to the actual mesh density. So alternatively...

9b. Height Map (greyscale) => Bump (numeric)

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.
