When vertices are sliding along the length of
the spline a nd you want them to bend and twist
based on the spline position, but don’t want vertex
weights to change, turn this option on.
Reassign Globally—Re-weights, and resets t he
position on the spline used for bending for moved
vertices globally. The vertex link assignment,
weighting, and spline pos ition are reset for all
moving points on every f rame. (This is equivalent
to Physique 2.2.) This option is like reinitializing
on every frame. D efault=off.
When vertices are moving to different envelopes
and you want them reassigned to the new
envelopes, use this option.
Hide Attached Nodes—Toggles the display of the
underlying skeletal system. This allows you to hide
and unhide the biped, for example.

“Floating” bones provide a way to use Physique
without using a biped character. The Floating
Bonesrolloutspecifiesthesplines,boneshierarchy,
or unattached bones you are using to defor m a
mesh. For example, Physique lets you animate
a mesh by animating spline vert ices or a bones
system. When you attach the spline or parent bone
to Physique, it creates envelopes for the selected
spline or bones.
Procedure
To hav e a spl ine infl uence a mesh:
1.
Create a spline and place it within a mesh that
has Physique applied.
2. Selectthemesh,andgotothe
Modify panel.
3. On the Floating B ones rollout, click Add.
A Select Bones dialog is displayed.
4. Use the Select Bones dialog to select the spline.
5. Animate the spline vertices to animate the
mesh.
Tip: If you want to control the mesh by animating
bones,followthepreviousstepsusingbones
instead of a spline.
