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.
Wisps ¶
Do Noise
If the toggle is off, the smoke will look like Basic Smoke.
Frequency
This value controls how “wiggly” the smoke wisps are. Low values give smooth wisps, where higher values result in patchy, more
frantic wisps. See 
voronoi for more information.
Offset
This vector positions the pattern in x, y, and z.
This vector can be used to animate the smoke. As an example,
a positive $T times some speed value in y, gives the appearance the smoke is rising.
A positive value in x with a negative value in z (or vise versa)
give a swirling appearance. See voronoi for more information.
Periodicity
This vector specifies how often the pattern repeats itself along each axis.
Zero turns this off. See voronoi for more information.
Wispiness
This value controls the size of the “holes” between the wisps.
Zero turns the wisps off and the smoke will look like Basic Smoke.
See voronoi for more information.
