To set spring attributes, select the spring object in the Outliner or scene, and then click the springShape tab. These attributes are also available in the Spring options window (see Springs Options).
Lets you set stiffness, damping, and rest length for individual springs. See Edit per-spring rest length, stiffness, and damping.
If you use the Attribute Editor to change the setting of Per-spring Stiffness, Per-spring Damping, and Per-spring Rest Length from off to on after you create springs, Maya uses the Stiffness, Damping, and Rest Length attribute values that apply to all springs in the spring object.
Sets the rigidity of the springs. If you increase the stiffness of springs too much, the springs might stretch and contract excessively (see Troubleshoot nParticle springs).
Note that you can adjust the bounciness of a colliding soft body by changing the stiffness.
Mutes the spring action. A high value causes spring length to change more slowly. A low value causes the length to change quickly. You can use a low Damping value and a high Stiffness value to create a jiggle effect.
Sets the length for the springs when they are at rest. Every spring in the spring object is set to the same Rest Length value.
The springs try to reach their rest length when you play the scene. If you set it to a value smaller than the length of the spring, the spring contracts when you play the scene. If you set it to a value that is larger than the length of the spring, the spring expands.
Sets the amount of the spring’s force applied to the spring’s starting point. You can enter a value between 0 and 1. A value of 0 means the point is not affected by the spring forces; a value of 1 means the point is fully affected.
Sets the amount of the spring’s force applied to the spring’s ending point. You can enter a value between 0 and 1. A value of 0 means the point is not affected by the spring forces; a value of 1 means the point is fully affected.
The order of particle creation establishes which spring points are the starting and ending points. Because it’s hard to know which points are the starting and ending points for a particle object with many particles, End Weights are easiest to use with springs between small numbers of particles.
