Here are some images about some more info and breakdown:
Bpr of Zbrush high res model:
I created a dynamesh model first then retopo it use Zsphere and finilize the model in Maya, and for the posed model I used TransPose Master.
About the hair and fur, I used polyon to model the hair planes first ,then converted them to subd then to nurbs finally converted to hair curves,and applied some hair systems for different hair layers.
the fur stuff like eyebrow,facial hair, beard, I used fiber mesh, I groomed them in Zbrush first, then I exported them to maya as curves, and applied the hair system to the curves. Really a lot of time saved by Fiber mesh. and for the hair render I used vray hair shader.
About the textures, color maps are done in photoshop. specular/bump maps was converted or just from displacement map generated from Zbrush. For exemple:
For Shaders , I used Vray mtl and Fast SSS for all models.For exemple the head shader is combined a sss shader and 2 vray mtl shader(for reflection,specular)
