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. WebOne of the most basic outline effects can be achieved by using a so called fresnel effectwhich can be used to render an outline on the rim/edge of an object. The fresnel effect describes the reflection/transmission of light when falling onto a transparent surface. Web17 de jan. de 2024 · What is a rim light?
