Broken normals in the motorbike set

Question

Version 2.79 (2.79 2017-09-11, Blender ) was used by to render

http://shapenet.cs.stanford.edu/shapenet/obj-zip/ShapeNetCore.v1/03790512.zip

The normals on these objects are bad, and will not subdivide correctly

It seems it could be as simple as the fact the normals are reversed.

Do you have any advice for working with this data set it was from the advice of the project:

Answer 1

ShapeNetCore.v2 should have improved normals.  Please let us know if you find this to be an issue with ShapeNetCore.v2 as well.
