Hi Laurent,

Thanks for the help, I tried to reduce the size but still there are some disturbances over the surface (shown in the figure),

Is it possible to use Octree based image instead of structured one? In this way I can reduce the image pixel size and

concentrate it over the skin surface.

In your case, I think only the facet_distance matters. Set it from 0.5 to 0.1.
