I picked this piece up again since the release of 4R7 64 bit. I have always had subdivisions in my models that I could not export or generate maps for because of the memory restrictions in previous versions. But now I can actually use every pixel in an 8192 texture and get that detail out of ZBrush.
So here is my first image using the latest version. It was sculpted in ZBrush and all the hair was generated using Fibremesh. I rendered it in Octane and did the lighting using HDR Light Studio.
I will post a brain dump soon, as well as some image variations.
The full sized image is here:
