inverted selection) move up toward the selected
vertices.
7. Turn off Invert Selection and slowly reduce the
Iterations to 0.
The object now looks as it did before you
applied Preserve.
8. Increase Iterations to the defau lt 25, and then
increase it to approximately 75.
The object is now almost completely spherical
again.
9. Set Iterations back to 25, and then try different
Edge Lengths, Face Angles, and Volume
settings. ( You can restore t he defaults by
settings E dge Lengths to 1.0, and Face Ang les
and Volume to 0.3.
Steps in applying the Preserve modifier to a geosphere
Ex ample: A nima ting a pr eser v ed object:
You can animate the Preserve parameters, but the
following procedure shows you how to use Morph
and Preserve together.
1. RemovethePreservemodifierfromthecopied
sphere, and go to object level (ins tead of
sub-object level).
2. Withthecopied(anddeformed)sphere
still selected, choose Create panel > Compound
Objects > Morph to make it into a Morph
object.
3. Make sure Instance is chosen in the Pick Targets
rollout.
4. At frame 0, click Pick Target, and then select
the original sphere.
5. In the Modify panel, go to frame 100,
select sphere02 in the Morph Targets list, and
click Create Morph Key.

deformed sphere.
6. Apply Preserve to the morph object.
7. Click Pick Original, and select the original
sphere.
The object now morphs from the sphere to
apreservedanddeformedsphere.Notethat
because the object selection is passed up the
stack, the Preserve effect is applied to the entire
sphere.
8. Choose Selected Verts Only in the Selection
group.
Now, only the selected vertices are affected by
Preserve. The morph still works, however.
Example: Using the S election check boxes:
1.
Reset the program, create a box, and convert
it to an editable mesh.
