Thats actully a ZB BPR render. I can go as high as 7 levels with my machine on most meshes. mesh back in maya is just a Dis map with color map that had Cavity and AO maps over it.

The wire frame a few post up is what came back into maya and i just added a smooth.

This is a older Dis map from the other day have not updated it from todays work, but gives ya a idea whats going on back in maya right now....
