Back > (when the object is seen from a low angle), refraction cannot occure and only reflection does.
Refraction occurs no matter what angle you look at the object. The index of refraction is a calulation of how light bends when passing through transparent material (water, glass) it has no bearing on how transparent the object is. You seem to be saying that refraction and transparency are the same thing and they are not.
> Since the Carrara optical model does includes a refraction indice, Carrrara should be able to render, without any extra plug-in, the so-called "Fresnel effect".
Not so, because refraction and Fresnel are not interchangeable. They are not the same thing. The Fresnel dictates how an object (dependent of the viewing angle) appears to go from transparent to reflective. It has nothing to do with how light refracts through said object.
