Hi Pilou, those look cool! But if you examine it closely I think you can see some of the artifacts being discussed.

For example here it looks like a visible seam appearing in the shading:



And here it looks like a sudden jagged bounce in the reflection:




Those are the kinds of imperfections that would actually be gone if vertex normals were being handled properly. It kind of gives an appearance of bumps or creases in those areas when probably the actual NURBS model was actually silky smooth there.


It's really sad to have such great quality for many of the other aspects of the rendering, but have problems in what is actually a really basic area.
