After
you attach hair curves to a fur description, a fur curve attractor
set is created. You can edit the attributes of the fur curve attractor
set at any time. The attributes define how the fur relates to the
hair curves. You can do this in the following ways:
Edit fur curve attractor
sets
When you edit a fur curve
attractor set, any changes you make apply to all the fur descriptions
assigned to that attractor set. The attributes are applied to each
hair curve in the set.
To edit fur curve attractor sets
- Select
Fur > Edit Curve Attractor Set and
then select the desired set of fur curve attractors.
- Edit the desired attributes in the FurCurveAttractors
node. For descriptions of these attributes, see
FurCurveAttractors node.
Randomly vary fur curve
attractor set attribute values
You can randomly vary fur curve attractor
set attribute values for a more natural effect using noise amplitude
and noise frequency. Noise amplitude refers to the variance of an
attribute, and noise frequency refers to the amount of variance
over a distance or area.
To set noise amplitude and noise frequency
- Edit the fur curve attractor set. For
details, see
Change fur curve attractor set attributes.
- Go to the Details section,
then go to the attribute for which you want to change noise values.
- Modify the Noise Amplitude and Noise
Frequency values. For more information see
Details.
Paint attractor set attribute
values
Just
as you can paint fur attribute values (see
Paint fur attribute values),
you can paint fur curve attractor set attribute values on an area
without changing the fur curve attractor set attributes for the
entire surface.
When you paint values
on a surface, Maya creates a map of the values for each of the fur
curve attractor set attributes that you change.
You can paint the following
fur curve attractor set attributes: Radius, Power, Influence, Start
Length, End Length, and Threshold
Length. For information about these attributes, see
FurCurveAttractors node.
You can also paint Attraction per fur description. For more information,
see
Attraction.
NoteYou cannot use Artisan to mask selected vertices
when painting fur curve attractor set attribute values.
TipBefore
using Maya Artisan to paint fur attractor set values, set and learn
the Maya hotkeys for at least the following commands:
- Under the Brush Tools category, ModifyUpperRadius.
- Under the Artisan category, ModifyPaintValue, FloodSurfaces, ToggleWireframeInArtisan, ToggleColorFeedback,
and ToggleReflection.
You will find these commands
increase your efficiency as you work with the Paint
Fur Attributes Tool.
To paint attractor set values
- Select the surface(s) you want to paint.
The selected surface must have a fur curve attractor set assigned
to it.
- In the Rendering menu
set select
Fur > Paint Fur Attributes Tool > . The Paint
Fur Attributes Tool Settings window opens, followed by
the Paint Scripts Tool editor.
- In the Paint Fur Attributes
Tool Settings window, modify the following settings:
- Fur
Attribute - Select attribute you want to paint values
for on the surface, one of the following: Radius, Power, Influence, Start
Length, End Length, and Threshold
Length.
- Fur
Description - Fur curve attractor sets affect all fur
descriptions attached to a hair system.
- Attractor
Set - Select the fur curve attractor set you want to
paint.
- In the Paint Scripts Tool editor,
select an appropriate Value, Profile,
and Operation. For details, see
Artisan Tool Settingsin
the Artisan guide.
- Drag the brush across the surface.
TipYou can quickly restore
attractor set attribute values to the prepainted values by deleting
the attribute map created when you painted the fur. For details,
see
To remove maps from an attribute.
To paint attribute values greater than
1
- Use the Paint Fur Attributes
Tool to flood the selected surface with an attribute
value of 1.
- Select the attribute from the Fur
Attribute drop-down list.
- Set the Value to
1.
- Click the Flood button.
- Set the attribute Map
Multiplier to the number you want to paint. For details,
see
Change attribute map value ranges.
You can now paint values between 0 and less than the value set for
the Multiplier.
- Map Multiplier
-
Set the
factor you want the value multiplied by. For example, if you want
to change the range of values for fur Length from
the default, 0-1, to 0-10, set the multiplier to 10.
Map attractor set attribute
values
Just
as you can map fur attribute values, you can map values for each
fur curve attractor set attribute by importing file textures. To
map fur curve attractor set attributes, follow the procedures for
mapping fur attribute values, but edit the attributes for the fur
curve attractor set instead of the fur description. For details,
see
Map fur attribute values.
Remember that because
Fur can use only simple file texture maps, every texture you import
must be “baked” to convert it to a file texture.
Change attribute map value
ranges
Changing
the attribute map value ranges will only have an effect if the attribute
has been painted or texture mapped. By default, attribute map value ranges
are defined to be between 0 and 1. You only need to change value ranges
when you want to paint or map values other than those defined in this
range. For example, you could change the range from 0.2 to 0.5,
2.0 to 3.0, or commonly, from 0 to 5. For information on painting
values, see
Paint attractor set attribute values.
For information on mapping values, see
Map attractor set attribute values.
You can set value ranges
for all attractor set attribute values.
To change attribute map value ranges
- Edit the fur curve attractor set. For
details, see
Paint attractor set attribute values and
Map attractor set attribute values.
- Go to the Details section,
then go to the attribute for which you want to change value ranges.
- Modify the Map Offset and Map
Multiplier attributes. For more information see
Details.
