Discussion at the TC-RTC forum site 
http://tinachepforum.forumup.co.uk/about208-tinachepforum.html has made 
me work again on the skin texture technique given to us by Ive a couple 
of years ago (2008/2009) for Poser figures. In the image below are some 
of the results using different figures and different settings for 
specular intensity and or diffuse roughness, from left to right: Simon 
(Poser 7), Alyson (Poser 8), and Anton Kisiel's Apollo Maximus.

I am still not sure about whether the bump sizes should be positive or 
negative. I find positive values looking better in general but that 
might be a wrong approach. Also the size of the highlights may be a 
matter of debate.

I shall post the code as it appears now to be in p.t.scene-files under 
the same header.

What do you think? I need a bit of feedback on this.

Thomas
