I use Shadermap 3, but for normal maps mainly.  It can make AO, and Displacement maps as well, but they don't translate well into Poser.  With the right tweaking in program, the normals are really rather good.  There are no bump maps on this render (It's WIP- still have tweaking to do in some areas), just displacement for the veins and the normals made in Shadpermap.
