Another use of the Grid Texture is for rendering via an external volumetric Shader such as the V-Ray Environment Fog. See the External Volumetric Shader section on the Tips and Tricks page for more information.

When doing Liquid simulations, Phoenix FD populates the grid Velocity channel only for cells / voxels inside the liquid volume - empty (air) voxels contain no velocity information. To generate velocity information for the empty voxels, enable Simulate Air Effects under the Liquid roll-out rollout of the simulator and re-run the simulation. |
...
Alpha is the Color's Intensity | alphaIntens – When enabled, the alpha for the texture will be based on the color's intensity. When disabled the alpha will be solid.
