You may want to assign materials to sub-object polygons as well as whole objects. One
approach is to use the Multi/Sub-Object material type briefly discussed earlier in the chapter
There is a much easier way to assign materials to sub-objects, however. Just select the
appropriate polygons on the surface (the object must be an editable mesh or poly, or have
an Edit Mesh/Edit Poly modifier applied), and assign the material as you regularly would
(using the Assign Material to Selection button or dragging the material to the selected
polygons in the viewport). A sphere with several polygons assigned to different materials
is shown in Figure 7.51.

Once you apply a material to a sub-object, a new Multi/Sub-Object material is created
in the scene automatically. You can load the new Multi/Sub-Object material by using the
eyedropper to click on the object in the viewport to load the material into a sample slot.
Maps
By now you??™ve noticed that the Material/Map browser has different maps you can access.
These maps are divided into categories.
You??™ve already used the bitmap map a few times.
