Rhinoceros 3D imported .obj give me mushy edges.

ZBrush Usage Questions
#1

Tried importing .OBJ objects from Rhinoceros 3D in order to Dynamesh add/subtract them in ZBrush. Was following the guidelines in the ZClassroom where he made a radio from imported .OBJ objects and he came up with relatively crisp objects.

When I try it, I get kind of mushy edges which Clay Polish does nothing to fix, it just seems to “melt” the tool slightly.

I’ve tried several mesh densities in the Export process from Rhino and was wondering would it be better to just model the original pieces in something like Blender where you work with Polys from the start as opposed to the Nurbs that Rhino converts to a mesh and then gets loaded into ZBrush? Does making it in polys from the start give a better final result than nurbs>polys?

Thanks.

You convert a nurbs model to poly and then export? I think there may be your issue. The way nurbs are converted to polys may create less than ideal meshes. Ideally you want only quads and fairly evenly spaced, only denser mesh where you want folds and detail. What you could try (untested) is generate a high density model, import into zbrush, use zremesher to generate a new low poly mesh and then project the imported high density model on that.
