deselected. If Clear Selection is off, the new
selection is added to any previous selection set.
Cle ar A l l—Removesanysmoothinggroup
assignments from selected polygons.
Auto S mooth—Sets the s moothing groups based
on the angle between polygons. Any two adjacent
polygons will be put in the same smo othing group
if the angle b e tween their normals is less than the
threshold angle, set by the spinner to the rig ht of
this button.
Threshold—This spinner (to the right of Auto
Smooth) lets you specif y the maximum ang le
between the normals of adjacent polygons that
determines whether those polygons will be put i n
thesamesmoothinggroup.
Edit Vertex Colors group
Use these controls to assign the color, illumination
color (shading), and alpha (transparency) values
of vertices on selected polygons or elements.
Co lor—Click the color swatch to change the color
of vertices on selected polygons or elements.
Illumination—Click the color swatch to change the
illumination color of vertices on selected polygons
or elements. This lets you change the illumination
without changing the vertex’s color.
Alpha—Lets you assign an alpha (transparency)
value to vertices on selected polygons or elements.
The spinner value is a percent age; zero is
completely transparen t and 100 is completely
opaque.

Paint Deformation rollout
Paint Deformation lets you stroke elevated and
indented areas directly onto object surfaces. For

Paint Deformation lets you push, pull, or
otherwise affect vertices by dragging the mouse
cursor over the object surface. At the object
level, Paint Deformation affects all vertices in the
selected object. At sub-object levels, it affects only
selected vertices (or vertices that b elong to selected
sub-objects), and recognizes s of t selection.

Note: Paint Deformation cannot be animated.

by using the

Procedure
To pa int d eforma tion onto a mesh object:
1.
Apply an Edit Poly modifier (page 1–619) to
an object, or convert the object to

format. Paint Deformation
uses existing geometry, so the object should
