Uniform Options

Use these options to control the behavior of your Uniform field.

Magnitude

Sets the strength of the uniform field. The larger the number, the stronger the force. A positive number pushes the influenced object away. A negative number pulls the object 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.

Direction X, Y, Z

Specifies the direction the uniform field pushes objects.

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 uniform field. Any connected objects outside the Max Distance are not affected by the uniform field.

If you turn off Use Max Distance, all connected objects are affected by the uniform field, no matter how far away they are from the uniform field.

Max Distance

Sets the maximum distance from the uniform field that the field is exerted. You must turn on Use Max Distance for Max Distance to take effect.

Falloff Curve

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.

Note: Fallout Curve is only available as an attribute after you create the field. It is not available an a field creation option.

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.
