WebRim lighting is a light that usually comes from beside or behind a subject, and enhances its silhouette. This shader fakes this by making use of the Fresnel effect. This can be used to stylize or highlight objects, and it greatly favors certain artstyles. It is especially pleasing when applied to smooth curvy models.
