RBD Angular Spring Constraint

Constrains the rotation of an object so it attempts to rotate naturally, but bounces back to its original rotation.

It will attempt to rotate naturally when it hits the ground plane but will bob back to its original rotation as a result of the spring constraint, which creates a wobbling effect. For example, this is can be used for an arrow hitting the ground.

You need to create an RBD object to apply this constraint to before you can use this tool.

Using RBD Angular Spring Constraints

  1. Click the RBD Angular Spring Constraint tool on the Rigid Bodies tab.

  2. Select the object to constrain and press Enter to confirm your selection.

  3. Select the position for the angular spring constraint and press Enter to confirm your selection.

    Note

    You can hold Alt to detach the constraint from the construction plane.

  4. Set the Strength and Dampening on the Spring tab in the parameter editor.

Note

To parent to another object, use the Parent Constraint tool.

For specific parameter help see the RBD Angular Spring Constraint dynamics node help.

Moving an RBD Angular Spring Constraint

  1. Click the Dynamics Select Mode button on the selector and handle controls toolbar.

  2. Click the constrained object in the scene view.

  3. Click the Dynamics Select Mode button and turn on the Dynamics Modifiers checkbox.

  4. Click the constraint you want to edit and press Enter to display the transformation handles.

Switching to the dynamics level

  1. Click the Dynamics Select Mode button on the selector and handle controls toolbar.

  2. Click the constrained object in the scene view.
