This dialog is launched from the Skin modifier
(page 1–781)
and provides tools to select vertices
and assi gn them weights. You can also copy, paste,
and blend weights b etween vertices. Each vertex

vertex must be selected.
Impor tant: The controls on this dialog adjust vertex
weighting with respect to the active bone; that is, the
object highlighted in the Bones list on the Parameters
rollout. When you select a vertex and then change
its weighting, if the active bone does not already
influence the vertex, the bone is added to the list of
bones influencing the vertex. You can ensure that bone
assignments don’t change by highlighting the bone in
the Weight Tool dialog list after selecting the vertex and
before changing weighting.
Also, the total weighting for all bones influencing a
vertex is a lways 1.0, so if multiple bones influence
a vertex and you change the weigh t value for one
bone, the weight va lues for the others change as
well.
