# I terations—

Sets the number of times t he fractal

function is applied. The higher the value, the

more deta il within the smoke, but the longer the

calculation time. Default=5.

Phase—Shifts the t urbulence within the smoke

pattern. Animate this parameter to animate the

movement of the sm oke. Default=0.0.

Exponent—Makes color #2, representing the

smoke, sharper and more wispy. As t his value

increases, the smoke "tendrils" become sm aller

within the pattern. Default=1.5.

Swap—Exchanges the colors.

Co lor #1—Represents the smokeless portion of the

effect.

Co lor #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 smok e 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 check box to activate

the map.

Speckle ma p used for rocks

Speckle is a 3D map that generates a speckled

surface pattern that’s useful for diffuse mapping

(page 2–1498) and bump mapping (page 2–1506)

to create granite-like and other patterned surfaces.
