Subsurface Scattering

(Credits : The Soldier, by Ribeyrolles Leo )

Substance 3D Painter supports Subsurface scattering both in its real-time viewport and in the Iray renderer .

Subsurface scattering is a mechanism of light when penetrating an object or a surface. Instead of being reflected, like metallic surfaces, a portion of the light is absorbed by the material and then scattered inside . This behavior is often known under the acronym SSS for " S ub S urface S cattering". Many materials in real life have subsurface scattering such as skin or wax.
