Poly Select Modifier 753
Using X For m M odif ier s to Ani mate a Poly
Selection
When you apply a Poly 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 using Poly
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,

selection.
•
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.
Procedure
To use the Poly S elect modifier:
1.
Create or select an object.
Note: Applying a Poly Select modifier to an
object other than a polymesh type wi ll convert
the object to a p olymesh object. If you want
more control over the conversion, add a
Tur n
To Poly modifier (page 1–863)
before applying
the Poly Select modifier. The Turn To Poly
modifier provides conversion options that
aren’t available with the Poly Select modifier.
2. Apply the Poly Select modifier.
3. Select vertices, faces, or polygons.
4. Add another modifier to affect only the
selection from step 3.
