I exported geometry to ZBrush where I added further details which can hardly be obtained by a common modelling software (picture 6); for this reason, I used a normal map (picture 7) in order to reproduce at best in XSI the result obtained with ZBrush. I chose a normal map instead of a displace one just for a question of time, the result wasn’t too much different and, in any case, there were no excessive deformations on the surface.

Once I exported everything to XSI, I created a lighting pass (picture 8) arranging a key light and a fill light with a key to fill ratio of approx. 1:2; I added a bump map too to reproduce the lack of homogeneity on the skin at best.
