That's incorrect. The Fresnel effect and the index of refraction are not the
same thing.

the effect would not be rendered by the rendering engine.
The Fresnel effect is the roll off of transparency to reflectivity (or
reflectivity to
transparency) on the surface of an object depending on the viewing angle.
The index of refraction takes into account how light bends (or refracts) when
passing through and object. The index of refraction has noting to do with how
reflecive an object is.
