If you click on the little red arrows of each window, the material windows will expand,
letting you change parameters. The first window shows a preview of the texture
and has the controls for applying the texture to your object. The second window
(Color) lets you choose a color, procedural shader, or image file. The third window
(Bump) is for bump maps/shaders and the third (Reflectance) is for the
reflectance maps/shaders.
For
the color or pattern, you can use either a procedural shader or an image file
(like a photo or a painted texture in formats like .jpg, .bmp, etc.). The
procedural shaders are based on mathematical formulas. They can simulate a lot
of different textures and are resolution independent, but they take longer to render. You can also have several
layers in your Material Editor, and mix-and-match shaders and image files, add
bump maps, reflectance shaders, transparency maps, etc. All these together make
up the material, which you can apply to your object, and which you can save into
the Material Library. Then, whenever you want to use the same material, you can
load it from there.
How
to load a procedural shader or an image map
You can choose a material from the Material Library, choose a procedural shader from the
Shaders library,
or load an image file for your texture. (Fig. 8.3)

To load a procedural shader, either
1. Click on the Color Shaders icon in the library panel
2. Or Right-click on the color icon in the Material Editor
3. Or Right-click inside the Color window.
This will bring
up the same Color Shaders library. Click on one of the shaders in this
library and it will be
loaded in the Material Editor. (Fig. 8.4)
To load an image file, either
1. Click on the Material Library, then click on the Caligari icon (Fig.
8.5) (If you have a different material library loaded than the one pictured
here, right-click in the Material Library window, scroll down to
"Load" and choose "materials".)
2. Or open the Color Shaders library (Fig. 8.6), then navigate to the Caligari icon and
click on it (Fig. 8.7). (See "To load a procedural shader" above on
how to open the Color Shaders library.)
