Magnitude

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.

Attenuation

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.

Radial Type

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.

Distance

Use Max Distance

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.

Max Distance

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.

Special Effects

Apply Per Vertex

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.
