Inter face

Size—Sets the size of the marble pattern. Change

this to change the sca le of marble, relative to the

object’s geometry. Default=50.

Leve ls —Sets the number of times the turbulence

algorithm is applied. Can range from 1 .0 to 10.0.

The higher the value, the more complicated the

marble pattern. Default=8.0.

Color 1 and Color 2 groups

The controls in these groups are identical. They

determine the two main colors of the marble.

Planet map u sed to create another world

Planet is a 3D map that uses fracta l math to

simulate the colors on the surfaces of a planet.

You can control the size of continents, percent of

ocean coverage, and so on. This map is meant to

be used as a diffuse map. It does not work well as

abumpmap.

Tip: TheMaterialEditor’ssampleslotdoesn’tshow

the planet effect very clearly. To help get the effect

you want, double-click the sample slot to get a

larger sample slot, or assign the map to geometry

and render the scene. Another way to preview the

planet map is to use the

Material Editor Options

dialog (p age 2–1280)

to set the 3D Map Sample

Scale to equal a main dimension of the object you

are applying the map to. For example, if you want

to use the planet map on a sphere with a radius of

20, change the map scale from 100 (the default)

to 20.
