FIGURE 32.5
The Flatten Mapping option displays every part of a model as a separate segment.

The Normal Mapping option lets you select to map a mesh using only specific views, including Top/
Bottom, Front/Back, Left/Right, Box, Box No Top, and Diamond. These views are based on the direction of
the normals from the faces of the mesh. It is helpful for thin models like butterfly wings or coins.
The Unfold Mapping option is unique because it starts at one face and slowly unwraps all the adjacent faces
into a single segment if possible. Figure 32.6 shows a simple cylinder that has been unwrapped using this
method. The advantage of this mapping is that it results in a map with no distortions. It includes two
options: Walk to Closest Face and Walk to Farthest Face. You’ll almost always want to use the Walk to
Closest Face option.

Note
Within a single mesh, multiple different mapping methods can be used. For example, a car’s wheel will use cylin-
drical mapping, but its hood might use planar mapping. Even a subobject selection can use different mapping
methods. n
