I would like to import, obj, mesh of a Rhinoceros in sculptis to model but i have the normal alternating triangles and the mesh is not workable. What are the correct parameters to build a mesh without defects? I thank all those who will respond ... I'm Italian and I have a bad English.
I noticed that sometime in Blender the .obj have inverted normals too, fortunately Blender in Edit Mode has a Mesh -> Normals -> Recalculate Outside that often fix that , or Mesh -> Normals -> Flip Normal for individual or groups of faces that are inverted.
If you're not confident with Blender, try Meshlab, load your Obj , click on Filters then on "Normal, Curvatures and Orientation" and see if one of the available option can fix it.
Meanwhile, thanks for the reply. I put a picture of a punctured polysurface. And 'labor is only half, half without the hole. I know that you are not many who work with Rhinoceros and I struggle to find answers in other forums.
Thank.....Please note, I use blender and I know that does very well with the OBJ file. They say that lightens them up. I'm looking for a direct route from Rhinoceros to Sculptris why I'm trying to save the various parameters of the mesh. If I find something I'll tell you. Thanks for now

I think the main problem (out of the disconnected vertices that makes the hole) is the hard edges, Sculptris is very bad with hard edges unfortunately.
Additionally, in the egdes of the object, the topology is rather horrible, maybe this is a problem with how Rhino exported that OBJ, but this topology nearly need a complete rework, it is surprising that Sculptris can actually open this without crashing.
By example, this quickly build OBJ that shape reminds a bit yours, in which the edges are very clean. I made some hard edges to see , and apparently Sculptris has no problem.
I think this may be the source of the bug you see, the edge topology that are not clean may be a problem for Sculptris tessellation.
There is a problem with your file. I open with the rhino, save it to obj but when I open it with sculptris so. Only imported without any intervention. Even worse if we subdivide the mesh. However maybe I can import something Give me a little 'time.
Here, Sanc, have centered in the middle of what is my problem. The export and save to OBJ, Rhino, give some problems. Should I find the right parameters. In fact, as you have shown you, all other graphics sw save spontaneously so that sculptris amounts correctly. I know the file from Rhino to Blender and then sculptris no problems. I just wanted to find a direct method. Hello
This group built and saved in OBJ with no problems on Rhino sculptris ......
