The BUNNY2 mesh contains lot of n-gons and the Geometry Input component supports only quads or triangles. Please follow the steps below to fix the mesh and let me know if you struggle.
- Import mesh to Rhino
- Run DeleteMeshNgons command
- Save as a new OBJ
- Upload to ShapeDiver
I uploaded this cleaned mesh and it worked fine.
