Look in the Library under Materials -> Superfly -> Superfly Tileable -> !Guide

You will find self explaining templates on how to hook up your maps for various PBR workflows.

I've had a look at those four templates (thanks hborre for the idiot's guide with pictures ;o).

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)

I'd suspected that a Roughness Map was effectively an inverted old-fashioned Specular Map.

But why does the new-style Specular Map need to be multiplied by 12.5 ?

Anyway, going back to my personal original question, i.e. how to use the plethora of new-fangled maps with a PoserSurface node and Firefly, I think that the only outstanding PBR map from that list is the Metallic Map.

So how would I usefully connect a PBR Metallic Map to a PoserSurface node ?

I should also point out that this thread is not specifically about PBR image maps: that's over there => Using PBR material sets?

The other main type of image map sets I'm interested in are the ones that come with models intended for games. These usually have a basic texture colour map plus a normal map, sometimes an AO map, and usually one or two others whose names match some of the PBR maps.

hborre mentioned earlier that AO maps aren't really necessary for Superfly, but I have a few models that only have the three maps - base colour map, normal map and AO map.

• How would folks recommend that I use the AO map for Firefly/PoserSurface ?
• How would folks recommend that I use the AO map for Superfly/PhysicalSurface ?
