When you apply a Mesh Select modifier, there
are no animation controllers assig ned to the
sub-object selection. This means t hat the selection
has no way to "carry" the transform information
needed for animation.
To animate a sub-object selection u sing Mesh
Select, apply either an XForm or Linked XForm
modifier to the selection. These modifiers prov ide
the necessary cont rollers for animating the effects
of t ransforms. In a sense, they give "whole-object
status" to the sub-object selection.

XForm (page 1–942)
Animates transforms directly on a sub-object
selection. Creates a gizmo and center for the
sub-object selection. You can animate both,

•
Linked XForm (page 1–703)
Lets you choose another object to control the
animation. The sub-object selection is linked to
the "control object." When you transform the
control object, the sub-object select ion follows
accordingly.

Show End Result—Normally , if you apply a
modifier such as Twist to an editable-mesh object
andthenreturntotheEditableMeshstackentry,
you cannot see the effect of the modifier on the
object’s geometry. But if you turn on Show End
Result, you can see the final object as a white mesh,
and the ori ginal editable mesh as an orange mesh.
Note: WithmodifierssuchasMeshSmooth,which
apply by default to an entire object, no special
treatment is necessary. However, if you intend to
use this functionality with other modifiers that
work on a sub-object selec tion passed up the st ack,
such as Bend, and you want to apply the modifier
to the entire object, you should place a
Vo lu m e
Select modifier (page 1–935)
between the editable
mesh object and the modifier in t he stack. You
should lea ve the Volume Select modifier’s level at
the top (the default: no sub-object level chosen).
