That mohawk-like hair on his head? XGen primitives (splines). Created in Maya, rendered in Softimage.

1. Export an ASS file with XGen stuff from Maya.
2. Set the PATH to include the Maya plug-ins\xgen\bin and bin folders.

   set PATH=%PATH%;C:\Program Files\Autodesk\Maya2014\plug-ins\xgen\bin;C:\Program Files\Autodesk\Maya2014\bin

3. Add the MtoA shaders and procedurals to the search paths in the Arnold Render Options.
4. Add an Arnold Standin property to a mesh and point it to the ASS file.
5. And that’s it!
