Converting Spring Effects to Key-frame Animations

Spring physics are automatically generated along with the primary animation and there's not a way to intervene with the results while it's simulating. However, Cartoon Animator provides a sampling mechanism for converting spring dynamics into animation keys.

  1. Create an object with spring dynamics.
  2. Open the Timeline, click the Spring button to show the spring track.
  3. Right-click on the spring keys, and choose the Sample Spring Key command from the context menu.
    • In primary Spring track: Right-click on the On or Off key for sampling.
    • In individual Spring Group track: Right-click on the On key for sampling.
  4. As you can see the spring dynamic is converted into animation keys.
    • In primary Spring track: All groups' keys are sampled. The sampled keys exceed the range of the spring on and off keys because the bouncing spring animations must be completely sampled.
    • In individual Spring Group track: Only the selected group's key is sampled.
  5. You can then delete/move the keys or edit the sampled spring poses directly.
