I just uploaded a new version of my skin shader for Octane 2.0. It now has displacement. I also optimized it a bit for speed and ease of use. If you build your models to real world scale, and plug a color texture into the "Color" slot with the gamma set to 2.2, it should just work.
I attached a small image of test renders of a model that is a work in progress. I started this model with a scan of myself I generated using my Kinect. I cleaned it up and sculpted details, as well as textured it in ZBrush. I have not tweaked any of the specular maps, but I am pretty happy with the result so far. On to the eyes next.
here's a link to the full size render:http://www.darkcel.com/images/LightTestRenders.jpg
