Figure 14-78: This region will not patch properly, but following patching Tip
#4 enables me to work around the problem.
when the splines are selected in the order
shown. I checked to make sure that four
splines were selected in a counterclockwise
order and that all their points were welded
together properly. Having worked through
the obvious solutions, it's now time to try
patching Tip #4. By selecting the splines in
the order shown on the right side of the
Figure, I no longer get an
error message.
The last area to patch
should be the triangular
region at the top back of
the head shown in Figure
14-79. Since there are
only three splines here,
the order in which these
splines are selected will
affect the polygon layout
of our patch. In all hon-
esty, you can select them
in any order you desire,
but to be consistent with
the work we'll be doing
throughout the rest of
this chapter, select them in the order shown
in the figure.
Spin your model in the Perspective
viewport to check for any unpatched areas
in your cage. When your whole cage has
been patched, bring up the Statistics win-
dow by pressing the <
w
> keyboard
shortcut. If any splines are selected,
Figure 14-79: Patching the triangular region in the order shown on the left
yields the polygon layout on the right.
