Step 23:
Mirror the mesh. Swap to object mode and select the face thus far.
Select Edit>Duplicate Special (Options). In the Duplicate Special Options
window choose Edit>Reset Settings. Change the Geometry Type: to Instance.
Change the Scale X input setting (the first column of Scale) to -1. Click the
Duplicate Special button to finish the mirroring of the geometry (
Figure 8.11
).

Mirrored geometry for
construction via Duplicate Special.
Why?
Scaling an object -1 in any direction will create a mirror version of the
object. By making sure this duplicate is an instance, we ensure that as
one side of the face is built up, this duplicate will also update. Now this -1
scaled half of the character will not be the one imported into Unity (the
normals are funky), but as a construction method, this works well to see
the whole face rather than just one half at a time.
Expanding Rings
Step 24:
Expand the rings. Change to edge mode and double-click one
of the outer edges (this should select the outer ring of edges). Choose the
Extrude tool and then immediately swap to the Scale tool and scale (by
dragging on the middle cube manipulator handle) this new collection of
edges out in every direction (
Figure 8.12
).
