Vertex Sub-Object (Physique) 1153
Vertex Type group
There are three vertex types, differentiated by
color:
•
Red—Deformable vertices that follow
Physique’s deformation spline.
•
Green—Rig id vertices that do not deform
but just follow t he link they are assig ned to.
•
Blue—Vertices attached to the root node.
Physique uses this color when it isn’t sure which
linktoassigntheverticesto. Thesevertices
don’t deform but follow the center of mass
object. You should reassign blue vertices to b e
either rigid or deformable.
While a button of the appropriate color is turned
on, you can select vertices of that color. Turn off a
button to avoid selecting vertices of that color. You
can’t turn off all three buttons at once.
Blending Bet ween Links drop-down list
This list provides several options:
•
NLinks—Ver tices within al l overlapping
envelopes are influenced.
While this option is active, vertices can be
assigned only to the envelopes they fall within.
Envelop es are used by Physique in this case to
define the blended weight of each vertex.
•
No B l ending—Vert ices are influenced by only
one link, as in character studio 1.
This is useful as a general default if you are
developing characters for a game engine
that doesn’t support blending. At the Vertex

For example, after selecting vertices of the skull
and face, turn on No Blending, turn on Rigid
ver tices, tur n on Assign To Link, and then
click the head link. This will override the head
envelope vertex assignments and assign these
vertices as ri gid to the head lin k. Use Lock
Assignments to lock any changes (see below).
•
2, 3, 4 Link s—Vertices are influenced only by the
specified number of clos est links. This is useful
when developing characters for a game engine
with limited blending.
Vertex Operations group

the m ain toolbar.
Select by Link—Selects vertices by link.
Assign to Link —Assigns the selec ted ver tices to a
link.
To assign the currently selected vertices to a link,
turn on Assig n To Link and t hen click the link.
Assign To Link has a dependency on the envelopes
defined for each link, and you must set Blending
Between Links to "N o Blending" to override
