Cycles includes nodes that model the passage of light through the objects interacting with them. One of these models is called shader calculation “Volume absortion”, it is especially suitable for working with transparent objects (used in combination with the shader “Glass” inter alia) o simular humo y nubes.
Incorporates Blender Cycles render volumetric imaging allowing increasingly realistic. Although the shader is in constant development, the degree of maturity that has largely simulates the behavior of light in different areas.
Next to simulate techniques such as participating media Scattering, the absorption of light along the volume of the scene allows us to play with its attenuation with distance from the emission source. A new node with which continue to experience in our classes.
