Retopology with ZRemesher and Maya Modelling Toolkit
Here's a demo retopologising with ZBrush's ZRemesher and the Maya 2014 Modelling Toolkit, no sound. Works pretty well total time 1hr 20 min and first time to use both tools after watching a couple of tutes. Lots of fiddly modelling in Maya as the ZRemesher is not perfect. Be sure to have your Maya shortcuts down!
Original Sculpt took 1hr. First 20 mins is here
