With the Paint
Cluster Weights Tool, you can use a Maya Artisan brush
to paint cluster weights on your deformed geometry.

The Paint
Cluster Weights Tool menu item is located under the Edit

Tool settings
Lets you specify the
settings for the Paint Cluster Weights Tool in
the Tool Settings editor. In the Paint
Attributes section there are some attributes unique to
the Paint Cluster Weights Tool.
These unique attributes are described below along with some of the
common attributes, and how they apply to this tool. For descriptions
of all other attributes in all other sections, see
Artisan Tool Settings.
TipYou can define hotkey
combinations to change most of the settings without opening the
Tool
Settings editor. For details on setting hotkey combinations, see
Use Artisan hotkeys.
Paint Attributes section
These are descriptions
of the attributes in the Paint Attributes section.
- clustern.weights jointClustern.weights
-
Displays the name of
the cluster selected to paint and the attribute you are painting (weights).
To select another cluster to paint, click this button and select
the appropriate cluster weights name. By default, the tool selects the
first cluster it detects on the surface (for example, cluster1.weights,
or jointCluster3.weights).
- Filter: cluster
-
Sets
a filter so that only cluster nodes display on the menu for the
button above this one. You are painting clusters with the Paint
Cluster Weights Tool, so you do not need to change this
filter.
Paint Operation
Select
which paint operation you want to perform on the selected cluster.
- Replace
-
Your brush stroke replaces the vertex weight with
the weight set for the brush.
- Add
-
Your brush stroke adds the vertex weight
to the weight set for the brush.
- Scale
-
Your brush stroke
scales the vertex weight by the weight factor set for the brush.
- Smooth
-
Your brush
stroke averages the weights of adjacent vertices to produce a smoother transition
between weights.
- Value
-
Set
the weight value to apply when you perform any of the painting operations.
- Min/Max Value
-
Set the minimum and maximum possible
paint values. By default, you can paint values between 0 and 1.
Setting Min/Max Value can extend or narrow
the range of values.
Negative values are useful
for subtracting weight. For example, if you set Min
Value to -1, Value to
-0.5, and select Add for the operation, you
would subtract 0.5 from the weight of vertices you paint.
Positive values are used
as multipliers.
TipTo help you differentiate
paint values when you paint with ranges greater than 0 to 1 (for example,
-5 to 5), and to maximize the range of values that display when
you paint values with ranges between 0 to 1 (for example, 0.2 to
0.8), set Min Color and Max
Color (in the Display section)
to correspond with the Min/Max values.
Clamp
Select
whether you want to clamp the values within a specified range, regardless
of the Value set when you paint.
- Lower
-
Turn this on to clamp
the lower value to the Clamp Value specified
below. For example, if you clamp Lower and
set the lower Clamp Value to 0.5, the values
you paint will never be less than 0.5, even if you set the Value to
0.25.
- Upper
-
Turn this on to clamp
the upper value to the Clamp Value specified
below. For example, if you clamp Upper, set
the upper Clamp Value to 0.75, and set Value to
1, the values you paint will never be greater than 0.75.
- Clamp Values
-
Set
the Lower and Upper values
for clamping.
- Flood
-
Click Flood to
apply the brush settings to all the weights on the selected cluster.
The result depends on the brush settings defined when you perform
the flood.
- Vector Index
-
If
you are painting a three channel attribute (RGB or XYZ), select
the channel you want to paint. Cluster weight is a single channel attribute,
therefore you do not need to change this setting.
