Parameters

Smoke Intensity	This is an overall brightener/dimmer for the smoke color.
Use Smoke Color	If this toggle is off, the smoke color is ignored. If both Point Color and Smoke Color are off, the default color is white.
Smoke Color	This is the color of the smoke.
Use Point Color	If this toggle is on, the smoke color is multiplied by any point color. If both Point Color and Smoke Color are off, the default color is white.

Density

Smoke Density	The overall density of the smoke. Higher values are more opaque smoke that reflects light faster.
Shadow Density	This is the same as Smoke Density but is used in the shadow pass. This controls how much light the smoke will block.
Receive Shadows	If this toggle is on, the smoke tests for light visibility. Enabling shadows also enables self-shadowing. Note For performance reasons, it is recommended to use Shadow Maps for shadowed smoke.
Illuminance Angle	This is the angle of the cone, in which the smoke will test for shadows.

Noise

Do Noise	If the toggle is off, the smoke will look like Basic Smoke
Frequency	The scale of the noise pattern. Larger values give smaller, but not more detailed, patterns. Smaller values will benefit from higher Turbulence numbers. See aanoise for more information.
Amplitude	The bounds of the noise function are multiplied by this value. The Density is multiplied by the resultant value. This then affects the opacity of the smoke. See aanoise for more information.
Offset	This vector positions the noise on the object in x, y and z. An additional w parameter is provided to allow animating the noise over time. See aanoise for more information.
Roughness	This value sharpens or softens the edges of the noise. Lower values are softer, higher values sharper. Sharper edges may cause aliasing issues in motion. See aanoise for more information.
Turbulence	This value controls the amount of details in the noise. This is the number of times the noise function is called and summed. If the Frequency is high, there is no need for much detail, 1 or 2 should be plenty. This can effects the Amplitude of the noise as well since the summing will result in higher base values. See aanoise for more information.
