Physical Force

A physical force is a spherical object with a force that is applied to its center and attenuates as follows:

Here:

Name	Description
distance	Distance between the sphere center and the object.
radius	Radius of the sphere in which the force is applied.
attenuation	Force attenuation factor.

All physical bodies and particles that are within the radius of the force are pulled up to or away from the center of the physical force node. Also the bodies and particles can be rotated around the center of the physical force node.

Notice

The physical force will affect particles only if their physical mass is nonzero. The physical mass for the particles can be set on the Params tab of the Nodes panel.

Notice

The physical force can affect only a cloth, a rope or a rigid body. If the rigid body is used, a shape should be also assigned.

Physical	Physical mask. The physical mask of the physical force must match the physical mask of the physical object. Otherwise, the physical force won't affect the object.
Radius	Radius for applying the physical force in units.
Atten	Attenuation factor indicating how much the physical force decreases when the objects move away from the force center.
Attractor	Attraction force applied to objects in the physical force radius. If a positive value is provided, objects will be pulled away from the force point. If a negative value is provided, objects will be pulled up to the force point.
Rotator	Rotation force that is applied to objects in the physical force radius. If a positive value is provided, objects will be rotated clockwise. If a negative value is provided, objects will be rotated counter-clockwise.
