to be made out of brick, you can choose a texture map with an image of bricks.
This is the most common kind of mapping. You can also use a procedural
map, such as tiles or wood. The procedural maps have properties you can
adjust for the effect you want; for example, the tiling size and mortar spacing
for a brick patterned material or the spacing of the grain in a wood material.
The map you add to a material can be scaled. The pattern can be tiled or
rotated.
Maps are also available for other purposes. You can use more than one map
for the same material and can create nested maps.
After you apply the map, you can adjust it to fit on the face or object by using
material mapping.
NOTE When Texture Compression is turned on, the amount of video memory
required to open a drawing that contains materials with images is decreased. By
using texture compression, the amount of video memory necessary to display the
drawing is reduced, but the time it takes to load the images the first time that
they are accessed is increased. Also, there is a reduction in the quality of the images
when they are displayed in the viewport or plotted. When you create a rendering,
there is no loss in image quality.
Reflectivity Map
Reflectivity maps simulate a scene reflected on the surface of a shiny object.
Use a reflectivity map to simulate a scene reflected on the surface of a shiny
object. For reflectivity maps to render well, the material should be shiny, and
the reflection image itself should have a high resolution (at least 512 by 480
pixels).
Transparency Map
Transparency maps create the effect of transparency and opacity.
You can specify areas of transparency and opacity by using the transparency
map channel. The effect of transparency is best previewed against a pattern
background.
Cutouts Map
Cutouts maps make the material partially transparent.
