Polygon Reduction
Nowthatwehavefinishedthetextures,wecanreassessthegeometryandremoveanything
that is no longer needed. The first area we can remove is where the polygons make up the
upper spine; these are shown in
Figure 9.50
, left. Because her crop top falls quite high
across hershoulder blades, wedon'tsee herspine, sothese polygonsare nolonger needed.

Remove the spine mesh detail.
1.
Snap the vertices to the inner ones and weld them. This should not involve altering
any UVs.
2.
The next area we can reduce is her navel. Originally, we built it in just in case we
needed detail in this area, but the texture does a good enough job at providing
definition. Select the vertices that make up the navel and weld them to each other,
adjusting the remaining vertex so it is in the correct place.
3.
The result should look like
Figure 9.51
, middle. The UVs need realigning slightly
in the UV Texture Editor, giving you the result in
Figure 9.51
, right.
