Hi Pilou,

very interesting. What i have tried now is to use Ngons/Quads, Mesh Angle 5
and then brought the mesh into Silo and applied a triangulation. My thought
was that then ZBrush must not compute so much when doing polygroups
from normals.

Maybe worth a try, because now i have all small ribs clean. In ZBrush i used
then only keep groups and did not use creases / edges feature.

I am sure your friend can archive much better results.



Regards
Stefan
