Hmm, there's a scatter scale now, so maybe they've adjusted the SSS settings in the PhysicalSurface node to the P-BSDF settings for Poser13? I'll leave it to the node whisperers to work out the details.

ETA: Anyway, the question was about the material settings I had used for a particular series of renders, not the *best* or *correct* settings. ;-) I've never claimed to know what the heck I am doing in the material room.
