I have a problem with vertex points. I’ve exported my model from Cinema 4D, via OBJ. The object is rendered correctly in Windows 3D viewer, and also in Cinema 4D (see below screenshots).
After I upload into the Sketchfab, some vertex points and edges are shifted a little bit and give a strange result (https://skfb.ly/6XnNy).
I’ve tried also via FBX format and gives the same strange result.
