Painting changes vertex weights relative to their
current values; it does not apply an absolute
weight. Longer strok es over an area of the mesh
wi ll increase or decrease vertex weights more than
short strokes, and repeated strokes over the same
area will cause incremental changes in weight
values unless they’re already at their extremes.
ThevertexcoloringshownatanyFlexsub-object
level provides an approximate indication of
weighting. The colors are determined by the
settings in Customize menu > Customize User
Interface > Colors tab > Elements: Geometry.
In this list are three color entries: Subselection
Hard , used to display ver tices with the h ighest
Weight values; Subselection Medium, used to
display vertices with medium Weight values; and
Subselection Soft, used to display vertices with low
Wei g ht v a lue s .
Strength—Sets the amount by which painting
changes weight v alues. Higher values change
weighting more quickly. At Strength=0, painting
does not change weight values. Range=-1 to 1;
Default=0.1.
Negative values allow you to remove weight.
Tip: When painting, you can use the ALT key to
invert the strength.
Radius—Sets the size of the brush in world units.
Range=.001 to 99999; D efault=36.
Note: If you position the mouse cursor over the
object before painting, you can see a wiref rame
representation of the spherical "brush" that depicts
the Radius setting.
Feath e r—Sets the falloff in strengt h from the center
of the brush to its edge. Default=.7. Range=.001
to 1.

Vertex Weights group
Sets ver tex weighting manually. At the Weights
& Springs sub-object level, select vertices in the
viewports, and then change the value of the Vertex
Weight parameter. Alternatively, turn on Absolute
Weight, set the desired Vertex Weight, and then
select vertices to set; changes are immediate.
Absolute Weight—Turn on to assign absolute
weights to the selected vertices. Turn off to add or
remove weight based on the Vertex Weight setting.
Vertex Weight—Assigns weight to selected vertices.
Depending on the state of the Absolute Weight
parameter, weight assignment is either absolute
or relative.
Note: The Vertex Weig ht range is -100 to 100.
With Absolute W eight on, the negative Vertex
Weight settings have no effect; t he effective range
is 0 to 100. With Absolute Weight off, changing
the Vertex Weight setting adds the amount to the
current weights of selected vertices, and then the
settingisresetto0.
