Subsurface scattering
ID: subsurface-scattering
Subsurface scattering (SSS) is a phenomenon in optics that occurs when light penetrates the surface of a translucent material, interacts with its internal structures, and then exits the material at a different location. This effect is particularly significant in materials that are not completely opaque and allow light to scatter within their volume, such as skin, wax, marble, and plants.
