Generic Spring

The generic spring constraint adds some spring parameters for the X/Y/Z axes to all the options available on the Generic constraint. Using the spring alone allows the objects to bounce around as if attached with a spring anchored at the constraint object. This is usually a little too much freedom, so most applications will benefit from enabling translation or rotation constraints.

If the damping on the springs is set to 1, then the spring forces are prevented from realigning the anchor points, leading to strange behavior. If your springs are acting weird, check the damping.

Options

Limits

• X/Y/Z Axis

  Enables/disables limit translation on X, Y or Z axis respectively.

  • Lower

    Lower limit of translation for X, Y or Z axis respectively.

    Upper

    Upper limit of translation for X, Y or Z axis respectively.

  X/Y/Z Angle

  Enables/disables limit rotation around the X, Y or Z axis respectively.

  • Lower

    Lower limit of rotation for X, Y or Z axis respectively.

    Upper

    Upper limit of rotation for X, Y or Z axis respectively.

Springs

• X/Y/Z Axis

  Enables/disables springs translation on X, Y or Z axis respectively.

  • Stiffness

    Spring Stiffness of the translation on X, Y or Z axis respectively. Specifies how “bendy” the spring is.

    Damping

    Spring Damping of the translation on X, Y or Z axis respectively. Amount of damping the spring has.

  X/Y/Z Angle

  Enables/disables springs rotation around the X, Y or Z axis respectively.

  • Stiffness

    Spring Stiffness of the rotation around the X, Y or Z axis respectively. Specifies how “bendy” the spring is.

    Damping

    Spring Damping of the rotation around the X, Y or Z axis respectively. Amount of damping the spring has.
