Right-click the Blue Onyx
material in the specification tree then select Properties (or
press Alt+Enter).
-
Access the Texture tab then select
Chessboard 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 tile and join colors:
- Tile Color represents the colored bricks and
corresponds to a color sequence. You can create a pattern with
squares in up to 4 alternating colors
- Join Color represents the color of the grid
pattern.
|
 |
-
Click the color square to select the desired color from
the Color chooser. You can also deactivate a color by clearing
the Enable option.
-
The Deformation
area lets you define:
- Tile Width and Height: sets the width
and height of the tile
- Join Width and Height: sets the width
and height of the join. This parameter allows you to simulate a
brick wall
- Offset: translates the join lines horizontally.
You can enter values comprised between 0 and 0.5, "0" meaning
that the join lines are in perfect adjustment. This parameter
allows you to simulate a brick wall, for instance.
|
The following are samples of deformation with
different tile, join and offset values: |
 |
-
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.
