Smoothness—Determines how sharp a cor ner
must be before polygons are added to smooth it.
Smoothness is ca lculated as the average angle of
all edges connected to a vertex. A value of 0.0
prevents the creation of any polygons. A value of

UVs button
Use these settings for specifying which map
channels to preserve when editing sub-objects
w ith the Preserve UVs option on. A preserved
map channel doesn’t respond to minor editing that
changes vertex locations, but a channel whose UVs
aren’t preser ved allows mapping to be changed by
changes in vertex locations.

data-containing vertex color channels and texture
channels. T he number and ty p e of buttons
displayed vary depending on the state of the
object; they can be changed, for example, with
the
VertexPaint modifier (page 1–918) and t he
Channel Info utility (page 2–1549) .
Click a button to toggle its state. When off, a
button is gray and appears higher than the dialog
surface. When on, a button is orange and appears
pressed in.
