Don't be afraid to experiment with the materials. I've included DS3 shader presets for the four examples shown here (unfortunately I didn't get round to doing this for Poser). If you're using DAZ|Studio try out these presets and have a look at the parameters on the surfaces tab. They're nothing special - I was just playing around, and you can easily come up with better ones yourself!

The 3Dcheapskate* occasionally posts sensible stuff. Usually by accident.
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.

*also available in ShareCG, DAZ, and HiveWire3D flavours (the DeviantArt and CGBytes flavour have been discontinued).
