1.28 Global Illumination in Participating Media2.1

Global illumination in volumes2.1can be used to simulate for example:

Global illumination in participating media is computed much the same way as global illumination on surfaces, except that volume shaders and volume photon shaders are needed.

To change the number of photons used to compute the local intensity of global illumination in volumes, specify a photonvol accuracy (and optionally a radius) in the options (similar to volume caustics).
