Unrecoverable error in SubSurf calculation, mesh is inconsistent.
anybody ever experienced this error message? I only saw it with 2.49 and in conjunction with Yafaray. But I get the suspicion that Blender 2.49 has a bug here.
The objects make the exporter crash. Only remodeling will hepl. Assigning new materials etc will not.
looks like a known problem - check this one out:
Blender corrupted the mesh completely and turned parts into - non-manifolds.
