The Volume Ramp (Gradient) node can connect to Absorption, Scattering, and Emission ramps in Volume Mediums.

It differs from a normal texture ramp because it is applied to just a Volume Medium node, and takes into account a given maximum grid value based on the grid indices in the volume data set.
