Right-click the Blue Onyx
material in the specification tree then Properties (or press
Alt+Enter).
-
Access the Texture tab then select Rock
in the Type list. You can also click the Ray Traced
Preview
button to display a preview of the material texture:
 |
When a
3D texture is selected, the corresponding texture image is
projected onto the object in the geometry area so that you can get
a better idea of the final result: |
 |
However, note that:
- the projected image does not reflect exactly what you get
when rendering the image
- the texture has a low resolution in order not to deteriorate
performance and as a consequence, the image projected onto the
object may sometimes be pixellised.
|
 |
You can also choose a
mapping type but do not forget that this mapping is relevant for
real time display only, it has no impact when computing the
rendered image.
Refer to Mapping Types
for detailed information. |
-
The Colors area lets you define two lighting
color effects:
- Material color: corresponds to the "background"
color of the object
- Color 1: corresponds to the color to which the
material color changes gradually
Click the desired color square to open the Color
chooser then select the color to apply. |
-
The Deformation
area lets you define noise parameters. Refer to
Noise Parameters for
detailed information.
-
The Bump area lets you
define an Amplitude value to add a lighting surface effect to the object.
You can use the slider or enter a coefficient value
comprised between -10 and 10:
- 0 means no bump effect
- 10 means that bright colors appear above
dark colors
- -10 means that dark colors appear above bright
colors.

Use the
Transformation area to adjust the mapped texture:
 |
- Scaling: stretches the
texture along X, Y, and Z axes
- Rotation: rotates the texture
around X, Y and Z axes
- Translation: translates the
texture along X, Y and Z axes.
