The Paint
Transfer Attributes Weights Tool lets you blend between
the source and target’s attribute values on a per vertex basis to
control the influence of either mesh on the resulting deformation.
The blending is controlled by an attribute map you paint on the
mesh using the Maya Artisan brush tools.
The Paint
Transfer Attributes Weights Tool menu item is located
under the Mesh menu in the Polygons menu
set (
Mesh > Paint Transfer Attributes Weight Tool).
NoteThe deformer weight
feature only applies to positional attribute transfers - all other
attributes will always be transferred with a weight value of 1.

Lets you specify the
settings for the Paint Transfer Attribute Weights Tool in the Tool
Settings editor. In the Paint Attributes section there
are some attributes unique to the Paint Transfer Attribute
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 in
the Artisan guide.
TipYou can define hotkey
combinations to change most of the settings without opening the Tool
Settings editor. For details on setting hotkey combinations, see Define
Artisan hotkeys in the Artisan guide.
Paint Attributes section
These are the descriptions for
the attributes in the Paint Attributes section.
- transferAttributesn.weights
-
Specifies the name of
the attribute being painted. When painting Transfer
Attribute Weights, this is <nodename>.weights.
Use this drop-down list to select other attributes to paint (for
example, the transfer weights of other transfer attribute nodes).
- Filter: TransferAttributes
-
Sets
a filter so that only transfer attribute nodes display on the menu
for the button above this one. You are painting Transfer
Attribute weights with the this 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
-
Replaces the vertex weight with the weight
set for the brush.
- Add
-
Adds the vertex weight to the weight set
for the brush.
- Scale
-
Scales the vertex
weight by the weight factor set for the brush.
- Smooth
-
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.
A value of 0 (black)
indicates that the original (un-deformed) mesh value should be used, whereas
a value of 1 (white) indicates that the value transferred from the
source mesh should be applied. Any value in between blends between
the two.
- Min/Max Value
-
Set the minimum and maximum possible
paint values. By default, you can paint values between 0 and 1.
Setting the Min/Max Values you 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 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. Attribute weight is a single channel attribute,
therefore you do not need to change this setting.
