Porous objects.

The scattering of a porous object is composed of Lambertian and non-Lambertian parts. The non-Lambertian part means its scattering is direction-dependent, which includes forward and specular scattering. For solid objects, such as soil and trunk, the forward scattering is minor and ignored.
