Hi Jamie, also one thing to note is that the default Blender OBJ importer also has a bug in it that discards the vertex normals instead of using them, so if you use Blender to test OBJ files with it could be easy to get a mistaken impression of what they are actually supposed to look like.

I have an updated version of the Blender OBJ import script which does not throw out the vertex normals here:

Maybe this is a source of some confusion, if imports into Blender were being used as some kind of model of how things are supposed to work...
