Subsurface Scattering Material

Updated: 4 Nov 2024

Method #

Subsurface Scattering is a technique that simulates how light penetrates the surface of translucent materials (like skin, milk, or wax), scatters within the material, and then exits at a different point. This effect creates a softer, more realistic appearance, especially for materials with depth, where light interacts below the surface.

This material needs the Path tracer node to function.

The output material can be applied to any node which accepts a material input, such as 3D Objects, Particle Trails, or a Procedural Raytracer.
