Figure 186: 3D Effects - Material
3D Effects - Material
On the Materials page of the Effects dialog (Figure 186) you can change the appearance of a 3D
object to represent different materials. Materials and textures can be combined with each other and
it is a matter of trial and error to achieve the desired result.
• Material – assigns a predefined color scheme or lets you create your own color scheme.
– Favorites – select a predefined color scheme, or select a custom color scheme that has
been user defined.
– Object color – select the color that you want to apply to a 3D object.
– Illumination color – select the color to illuminate the object and brightening parts of the
object which lie in shadow making the object seem more illuminated.
• Specular – sets the light reflection properties for the selected object simulating the
reflecting capacity of the surface. The position of the illuminated point is determined by the
setting of the first light source.
– Color – select the color that you want the object to reflect.
– Intensity – enter the intensity of the specular effect.
• The Color icon opens the Color dialog allowing you to define your own colors using
the two-dimensional graphic and numerical gradient chart.
Tip
Do not use a very high brightness values for individual colors. These are all
additive and it is easy to end up with a colored area that is white.
When you use individual color parameters additional effects can be produced, which are similar to
the color parameters in “3D Effects – Illumination” on page 151.
Note
Metallic and glass surfaces do not simulate well because the appearance of these
materials is produced using reflection.
