Today into Rhino we can export a Rhino Subd under .obj format with the OBJ subd option but we are limited by the .obj format capabilities.
For example, we are loosing connection (welded data) on the sharp edge vertices, and other warranty of the data consistency due to the .obj.
Could we have or expect an .fbx export process for Rhino Subd, compatible with blender ?
That is a function of how Rhino meshes work. Hard edges between faces are never welded.
In Blender merge coincident vertices using mesh.remove_doubles (Mesh > Clean-up > Merge by Distance).
Thanks Nathan for your answer. My problem is that when i use “Merge by Distance” in Blender it’s not a warranty for a good merge due to the possible proximity between vertices in a complex model.
Actually to correct this, it’s possible to weld vertices with the .obj export in Rhino. It’s why i’m asking if a .fbx export for .subd would not be a better way to transfert .subd data with a native weld process for hard edges ?
I don’t know if the welding for FBX would yield any different results.
Yes, today with the .fbx I’ve no possibility to export my Subd model. When I try to export a Subd Mesh with .fbx export options on each hards edges I can’t export only one welded vertex.
It would be very usefull to have the same option than for the .obj process.
Vertex → possibility to weld
And the most important function to keep Subd network integrity
Export Subd Mesh → Use the control network
