colors for different color components. You can set the color by
clicking the color swatch to display the
NoteThe Metal shader
does not have a Specular component, because it generates the specular
color automatically. The Multi-Layer shader can have two different
Specular color components, so for this material the Specular color swatches
are found in the Specular Highlights group. The Strauss shader has
only a single color component, which corresponds to Diffuse.

2. Diffuse color
3. Ambient color
Copying and Locking Color
For convenience in changing
color components, the Material Editor lets you copy one color component
to another by dragging, and to lock two color components together
with the lock buttons to the left of the Ambient and Diffuse, and
Diffuse and Specular color swatches.
When you drag and drop
a color swatch, the
or Swap Colors dialog asks if you want
to copy the color or swap the two colors.
In general, materials
with two identical color components do not look realistic, and except
for materials that are close to solid black, you should avoid using
copied or locked color components in materials you use in a scene. Color
copying and locking are best used as conveniences when you design
a new basic material.
Shortcut Map Buttons
The small buttons to
the right of the color swatches access the
where you select a map for that component. These buttons are shortcuts:
you can also use the corresponding buttons in the
rollout If you have assigned a map to
one of these color components, the button displays the letter M.
An uppercase M means that the corresponding map is assigned and
active. A lowercase m means that the map is assigned and inactive
The lock button to the right
of the Diffuse map button locks Ambient mapping to Diffuse mapping.
It is on by default. Usually it makes sense to use the same map
for the ambient and diffuse components. To use different maps for ambient
and diffuse, turn off the lock button. A map shortcut button for Ambient

To lock two color components:
- Click the lock
button between Ambient and Diffuse or between Diffuse and Specular.
The Material Editor displays
an alert that asks whether you want to lock the two color components.
- Click Yes.
The color above replaces
the color below. In other words, Ambient replaces Diffuse and Diffuse
If two colors are locked,
and you lock the other two, all three component colors are replaced
by the active color.
While two colors are
locked, adjustments to one color component affect the other as well.
To unlock two color components:

in direct light.

of the highlight on a shiny object. You can control the size and
shape of highlights in the Specular Highlights group, described
