To create a Gr a dient ma p:
1.
Clickamapbuttontoassignamap.
2. Choose Gradient in the Material/Map Browser,
and then click OK.
To change a gradient color:
1.
In the Gradient Parameters rollout, click a
color swatch to display the Color Selector (page
1–161).
2. Adjust the color .
3. Click one of the other color swatches.
4. Adjust the color .
To choose the kind of gr adi ent:
• Choose either L inear or Radial.

another along a line. A radial gradient has one
color on the inside and another on the outside,
shading in a circular pattern.
To us e a map for a color in the gra dient:
• In the Gradient Parameters rollout, click a map

To adjust the position of the second color:
• Change the Color 2 Position value.

between the first and t hird colors. For a linear
gradient, the second color’s position ranges
from the bottom at 0.0 to the top at 1.0. For
a radia l g radient, the second color’s position
rangesfromtheinsideat0.0totheoutsideat
1.0.
Interfa ce
Color #1-3—Sets the three colors that the gradient
interpolates between. Displays the Color Selector
(page 1–161). You can drag and drop the colors
from one swatch to another.
Maps—Displays a map (page 3–968) instead of the
color. Maps are blended into the gradient in the
same way that the gradient colors are blended.
You can add nested procedural gradients in each
w indow to make 5-, 7-, 9-color gradients, or more.
The check boxes enable or disable their associated
maps.
Co lor 2 Position—Controls the center point of the
middle color. The position ranges from 0 to 1.
When it is 0, color 2 replaces color 3. When it is 1,
color 2 replaces color 1.
Gra dient Type—Linear interpolates the color based
on the vertical position ( V coordinate) while
radial interpolates based on the distance from the
center of the map (center is: U=0.5,V=0.5). With
