This dialog is launched f rom the Skin modifier
(page 1–791) and provides tools to select vertices
and assign them weights. You can also copy, p aste,
and blend weights b etween vert ices. Each vertex
youselectdisplaystheobjectscontributingtoits
weighting in the dialog list.
To use these tools, Parameters rollout > Edit
Envelopesmustbeon,Parametersrollout>Select
group > Vertices must be on, and at least one
vertex must be selected.
Impor tant: The controls on this dialog adjust vertex
weighting with respect to the active b one; that is, the
object h ighlighted 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 always 1.0, so if multiple bones influence
a vertex and you change the weig ht value for one
bone, the weig ht values for the others change as
well.
