Using Poser 13's default "Mondello Beach", you  don't need any light- The default scene has one default light that has no effect on the render, as the scene is lit by the HDRi picture.

Example:

The said preview light has its Diffuse and Specular values set to black:

To be honest, the Sun intensity value is too high.  If you are using Superfly rendering and relying on HDRI illumination as well as an infinite light, I would reduce the sun intensity value.  Whenever I create an outdoor scene with a combination of HDRI and physical lights, the intensity value of the lights are decreased tremendously.  I have used values of 50% or lower, depending on how much of an influence I want the HDRI to impact the scene.

Under the Parameters tab in the Parameters panel for the light there is a 'Shadow' dial.  By default, that value is set to 1.000 (100%).  Shadow values should never be set to 1.  Try reducing that value until you achieve a more realistic render.

What kind of lights are you using?

You will notice in the one that Caisson used, that the lips are darker in the Roughness map. This makes the lips shinier. 

Can you answer one question though?  Is that a "Specular" map, or a "Roughness" map that you have connected to roughness? It looks like it might be Specular, which works differently. I will work up an example for Specular map connections.

Wherever you'd like to add glossiness (skin, lips, etc), if you don't  want to touch the base skin settings, you can add a second layer and this:

Till now, I'm not completely convinced by playing with the roughness/specular settings of the PrincipledBSDF node.
Adding a second layer allows you to better control the effects, at least it works for me as I've written a script for this.

And don't forget that with Poser12's last iteration, you may even save the second layer separately, for later uses.

Thank you Y-Pill. That's a very simple way. I love it.

The Physical Surface node and the Principled BSDF node work much better with metallic and roughness maps than with specular and gloss maps as used in older Poser shaders.  Specular maps typically show shinier areas as lighter colors. Roughness maps are the opposite, they show shinier areas as darker colors.  It’s not a simple matter of inverting the specular map to turn it into a roughness map. There are other differences as well.  There is a “Gloss/Specular Converter” compound node furnished with Poser 11 and 12 that will help make Specular maps work correctly with the Physical Surface and Principled BSDF nodes. 

1) Go to the Poser 11 (or 12) Content > SuperFly Tileable > !Guide folder. In there, you will find a Spec Gloss PBR shader.  Select a PREVIEW material in your scene (do not apply it directly to the character’s skin). After you apply it you’ll see a whole bunch of different images with text guides attached to the physical surface node. You don’t need those. ONLY copy the Gloss/Specular Converter node. After you do that you can delete all the maps connected to the root node.

2) Copy and paste that Converter node into your figure’s head material.  (There is a red outline around this node in the screenshot). 

3) Drag and drop the Specular image for the head texture into the material editor. NOTE that you will need to set the Custom Gamma to 1 for ANY map that is not a color map. This will be true of bump, displacement, specular, metallic, roughness, AND normal maps (the reason your preview squares look funny in the material room is because your normal map is not using custom value of 1). The only map that should use the default gamma settings is the diffuse map. The shininess on the lips in this case is ALSO coming from the specular map.

4) Connect the Specular Map to the Specular INPUT connection, and adjust the color chip to choose a light to medium gray color. Pure white will add too much shine.  Also, set the Gloss setting to around .1 for starters. Adjust both settings until you are satisfied with the results on the skin.

5) Connect the Roughness and Specular outputs from the Gloss/Specular Converter Node to the Roughness and Specular inputs of the Principled BSDF node.

6) Adjust your Subsurface Radius to 0.004820, 0.001690, 0.001090. This is a good value for caucasian skin.  For darker skin, try 0.003670, 0.001370, 0.000680

All the other skin materials in your character will need these changes done as well. Lips, torso, and limbs.  You’ll also notice that instead of assigning a subsurface color, I put the skin textures through an HSV node, and adjusted the saturation and value to .95 of the original. This would use a slightly grayer and darker version of the skin texture colors for the SSS.

I was really touched by your kindness.

Have you tried increasing the specular value higher?  And from what I see, your Surface value is too high.  Decrease that value to a starting point of 0.01.  Your teeth are showing a self-glowing effect.

@hborre Thank you for your kind explanation.

@Hborre Thank you  for sharing how to import G8 character in P12.

I already succeeded in importing G8F, morph, pose & expressions.

But I failed to import clothes.

Please read my thread, G8F cloth cr2 and help me.

Is the prop version on the figure? I.e. select the G8 figure, then look at the prop list.

Or, look in the hierarchy window.

In the hierarchy window also...

 I'm sorry I can't help you further on this.
