Use these options to control the behavior of your Radial field.
Sets the strength of the radial field. The larger the number, the stronger the force. A positive number pushes objects away. A negative number pulls objects toward the field.
Sets how much the strength of the field diminishes as distance to the affected object increases.The rate of change is exponential with distance; the Attenuation is the exponent. If you set Attenuation to 0, the force remains constant over distance. Negative numbers are not valid.
Specifies how the radial field’s effect diminishes with Attenuation. A value of 1 causes the effect of the radial field to drop quickly to zero when an object approaches the Max Distance from the field.
A value of 0 causes the effect of the radial field to gradually approach (but never reach) 0 as it approaches the Max Distance from the field. Specifically, the force at any position is determined by the ratio of the distance and Max Distance. If you use a value between 0 and 1, Maya uses a linear blend between the two attenuation effects.
If you turn on Use Max Distance, connected objects within the area defined by the Max Distance setting are affected by the radial field.
If you turn off Use Max Distance, connected objects are affected by the radial field no matter how far away.
Sets the maximum distance from the radial field that the field is exerted. You must turn on Use Max Distance for Max Distance to take effect.
Available when Use Max Distance is checked.
When using a field to exert force, sometimes the object receiving the force may have trouble settling down after the force is exerted. Use this curve to modulate the force. For example, scale the field’s force so that it smoothly drops off to zero at the boundary defined by the Max Distance value.
The curve is defined within the normalized distance; in other words, 0 to 1, where 0 corresponds to the field's center and 1 corresponds to the Max Distance value. The value from the curve is a scaling factor to be applied to the force.
Volume determines the region where the field affects particles/rigid bodies.
Choose one of None, Cube, Sphere, Cylinder, Cone or Torus.
When Volume Exclusion is turned on, the volume defines the region in space where the field has no effect on particles or rigid bodies.
Offsets the volume from the location of the field. If you rotate the field, you also rotate the offset direction because it operates in local space.
Offsetting the volume changes only the volume’s location (and therefore, which particles the field affects). It does not change the actual field location for purposes of computing field force, attenuation, etc.
Defines the extent of rotation for all volumes except cubes. This can be a value from 0 to 360 degrees.
Defines the thickness of the solid portion of the torus, relative to the radius of the torus’s central ring. The radius of the central ring is determined by the field’s scale. If you scale the field, the Section Radius will maintain its proportion relative to the central ring.
Sets where the field emanates from the object. If you turn on Apply Per Vertex, each individual point (CV, particle, vertex) of the chosen object exerts the field equally at full strength. If you turn off Apply Per Vertex, the field is exerted only from the average position of the specified points.
If you are using the Attribute Editor, open the Special Effects section to display the Apply Per Vertex attribute.
