Hi follewed the .pdf tutorial in Pixologic homepage.
Mesh build in XSI and UV assigned
Export in Z
Subdivide many times
save the obj
Export the displacement a at 4096 resolution
import with alpha factor the obj and displacement.
All work fine, but when i render i loss some tiny detail , my opinion is like to be a little blurred....
The render isn't crisp and clear like in Zbrush, and sometimes i can see some edge texture....
P.s. In Zforum i've seen so many render in Maya and M.R. very close to zbrush render
Thank's bye Leo
