hi RMA team, I went to export a SubD model from Rhino to keep working with it in Modo. The only way I know how to do this is _ExtractControlPolygon and export that as either OBJ or FBX. OBJ has been broken for a while and this week FBX broke too. edit: running (7.0.20140.14505, 05/19/20) Test cub…

Hi Gustavo- if you un-check ‘Create NGons’ in the OBJ settings, does the export do what you expect? -Pascal

hi @pascal , for that particular cube yeah the problem goes away, by introducing another problem, look what happens with the Ngons in my file: I export this (right cube has Ngons) [capture_gf_022212PM_200521] I get this in Modo: [capture_gf_022021PM_200521] I proposed a new setting for all mes…

@tim - do you think it is possible to have a ‘Preserve nGons’ as well as ‘Create nGons’ check box? @gustojunk - does this item correctly address the export problem for nGons? RH-58695 Export : OBJ - Allow preserving existing nGons -Pascal

Also what about solving those weird normal maps generated from extract control polygon. We do want good/usable normal maps. We don’t understand why _ExtractControl polygon is grabbing the normal maps from the smooth SubD. Any reason/utility on that?

@gustojunk - I think you mean that the vertex normals are welded on the extracted control polygon, correct? Not having those welded seems not to affect SubD creation (from them) in Rhino - if it is OK downstream as well (Unweld, 0 degrees to test) I imagine that can be fixed - I do not know if ther…

Hi Gustavo - can you please close Rhino, and run a repair on the WIP inastallation via the Windows control panel > Programs? Does that sort anything out for fbx? -Pascal
