The ultimate intention is to do it with isoblobs and real displacement
based on the texture. In fact I first modeled the figure in isoblobs
using iso_csg, and I do have an early render with a displacement using
a granite texture (attached), but I switched to regular blobs and
normals for development purposes. I tried one overnight render with
this complex texture but I was very slow. I was using the adaptive max
gradient like a good little doobie which is probably why. I expect I
can get good results cheating on the max gradient but it will still be a
long render so I am trying to put together a little nicer setting to go
along with it.
Here is some picture of Boli

Here the fissures have more of a crevice quality which should be a
relatively easy effect. The one I was studying in the Metropolitan
Museum, however, shows more of a flaking effect with the edges at the
cracks scalloped outward more.
