Yes, that's it.
Initially I didn't implemented this functionality because I noticed that some components don't have good looking normals and the embedded algorithm is generate better looking ones. (However I found some models with good looking embedded normals).
I opened your model with FreeCad and it looks the same as kicad render.

In fact, I tried first your model without loading that file embedded normals and it seems that algorithm generation of normals hangs.. (or it take forever to calc your 5Mbyte model! .. :S)

Maybe in future we can have an option to render the models flat or smooth.
As I suggest you may try play with some 3D editor and see if it is possible to improve and simplify your model.
You can try also remove from your file the normals and normal indexes... and see what happen.. 

what you see in your model that is not looking good is a well known issue in normal calculation. You can see that it is where are sharp edges in the model. so probably the software that generate it don't have a perfect algorithm.

Hi Mario

I did not manage to test your patch before it got committed in rev
5040, fine. But I have now tested it and the offsets and the rotations
are good now.

I do note that the big connectors I have are strange looking, I guess
that is the thing about the "normals" you were talking about. They
rendered fine before, but is it because the normals are inside out?
