The Volume Cloud procedural texture produces a 3D, volumetric cloud texture. The results can be visualized by changing the Time prarameter (figure 1).

Time - Provides control over animating the texture effect allowing for visualization of the 3D volume generated by the effect.
Sun Direction - Adjusts the direction of the illumination on the cloud.
Transform - Positions, scales, and rotates the surface texture.
Projection - Sets how the texture projects onto the surface.
