Smoke is a 3D map that generates amorphous, fractal-based turbulent patterns. It's primarily designed for animated Opacity maps to simulate the effects of smoke in a beam of light, or other cloudy, flowing effects.

Smoke map used to create clouds in the sky
Interface
- Size
-
Changes the scale of the smoke "clumps." Default=40.
- # Iterations
-
Sets the number of times the fractal function is applied. The higher the value, the more detail within the smoke, but the longer the calculation time. Default=5.
- Phase
-
Shifts the turbulence within the smoke pattern. Animate this parameter to animate the movement of the smoke. Default=0.0.
- Exponent
-
Makes color #2, representing the smoke, sharper and more wispy. As this value increases, the smoke "tendrils" become smaller within the pattern. Default=1.5.
- Swap
-
Exchanges the colors.
- Color #1
-
Represents the smokeless portion of the effect.
- Color #2
-
Represents the smoke.
Because this map is usually used as an opacity map, you can adjust the luminance of the color values to alter the contrast of the smoke effect.
- Click a color swatch to change the color. Usually you only need to do this to adjust luminance.
- Click a map button to assign a map instead of a solid color. Turn on the checkbox to activate the map.
