Proceed to the next key frame and continue to
change settings for the cur rent operation and
sub-object selection.
If you change the selection, the exist ing
animation is applied to the new selection, and
lost from the previous one. If you change
the operation, any changes from the previous
animation are f rozen (that is, “baked” into the
model) at the current frame, and only new
keyframes are recorded in the current Edit Poly
modifier.
To animate different sub-object selections us ing
different operations, use multiple applications
of the Edit Poly modifier.
To apply an Edit Poly operation to a n animated
sub-object selection:
This procedure demonstrates procedural
animation with Edit Poly: the ability to change
the location of application on an object during an
animation using an existing, animated sub-object
selection.
1. Select an object.
2. Create an animated sub-object selection. One

modifier (page 1–952) and animate the gizmo’s

using an animated texture map.
3. Apply the Edit Poly modifier.
4. Gotothesamesub-objectlevelinEditPoly,
and then, on the Selection rollout, turn on U se
Stack Selection.
5. Scrub the t ime slider.
The animated selection appears on the Edit
Poly object.
6. On the Modify panel > Edit Poly Mode rollout,
choose Animate.
7. Perform an operation on the sub-object
selection, such as a chamfer or extrusion. You
needn’t turn on Auto Key or use S et Key.
Note: With Use Stack Select ion on, you can’t
change the selection.
Now, when you play the animation, the Edit
P oly effect moves along with the animation of
the sub-object selection.
If you decide to animate a different function
procedurally, first click Edit Poly Mode rollout
>Cancel.
