The FurCurveAttractors node is created when you attach a hair system to a Fur description. The following attributes are available for this node.

For more information, see Change fur curve attractor set attributes and Fur > Edit Curve Attractor Set.

FurCurveAttractors

Replace the default name for the fur curve attractor set with something meaningful (for example, windCurveAttractors).

Curves Per Fur

Type the number of curves a fur should be influenced by. Use the following attributes as guidelines:

1—Every fur is influenced by the curve closest to it.

2—Every fur is influenced by the two closest curves.

3—Every fur is influenced by the three closest curves.

Global Scale

Use this setting to adjust the Radius, Power, Influence, and Length values by a common factor (including mapped values). The default is 1.0. For example:

NoteIf your fur doesn’t move during the simulation, check to make sure the multiple of the Global Scale and Threshold Length values (FurCurveAttractors node) does not exceed the Length value (FurDescription node). When it does, fur is not influenced by curve attractors. For example:

Threshold Length (0.33) * Global Scale (10) = 3.33

If the length of the fur description was 1.5, it would not be influenced by curve attractors, because the global scale value has made the threshold length 3.33, which is greater than 1.5.

Bake Attribute

Specify the attribute or all attributes to be baked.

Radius

Set the radius in which to search for the closest curves, in world units. This value can help prevent fur strands from being influenced by curves that are unreasonably far away.

Power

This attribute is only available if you are using Global as the Attractor Model type. Use Power to set how the curve will influence the fur strands. The value you enter is the power to a falloff function that makes fur become less influenced at the base of the fur than at the tip.

0.0—The entire length of the fur is influenced.

1.0—Fur is much less influenced at the base.

Influence

Set how much influence the curve will have on the fur. The value you enter linearly increases or decreases the influence over the length of the fur. Use the following attributes as guidelines:

0.0—No influence.

1.0—Standard influence.

If you are using Global as the Attractor Model type, then you can use a higher value than 1.0 for more influence.

Start Length

Set the point along the fur, in world units, at which the fur will start being influenced. In general, this value should be 0.0, unless you want the fur to grow in its normal direction up to a point along the fur.

End Length

Set the point along the fur, in world units, at which the fur will no longer be influenced. For the best effect, this should be at least as large as the longest fur length. With smaller values the tips of the fur will not be influenced.

NoteIf you add Noise Amplitude from the Length section to your fur description, the End Length should be longer than the fur length to account for the extra length created by the noise.

Threshold Length

Fur strands shorter than this value will not be influenced at all and will therefore not move. Use this value to prevent short fur strands from being influenced while long fur strands are influenced.
