Hello,
I have trouble getting a “clean” displacement map from zbrush… 
please see the attached image…
there are basically two problems:
-
zbrush creates details in the map that where actually not painted… it looks like a projection of the original mesh into the displacement map…
-
zbrush creates dark outlines around the painted details (I used the standard brush)… so when rendering outside zbrush I get a cavity around each painted detail…
please help… :-/
thanks,
Vadim
