Spring Track (New for 5.4)

The actors and the props (with bone structures) in iClone may sometimes contain extended bones. Although the extended bones are not included in the standard bone structure for motion puppeteering, they can be given Spring Effects. When the actors or the props are moving, these extend bones will automatically bounce along with the movements.

The Spring Effects can also be turned on and off as keys in a private track.

1. Select the object that has already had the spring effect applied.
   
2. Move to another time frame when you want to stop the spring effect.
3. Click the Off button in the Dynamic section of the Modify panel.
   
4. The object will be frozen and still when the spring effect is off.
   

Blending Keys

In case the spring effect starts or stops abruptly, you can use the blending keys (fade in and fade out keys). The blending keys ensure the spring effect gradually goes on and off.

A - Spring Fade Out Start key. B - Spring Off key C - Spring fading out duration D - Spring Off duration E - Spring Of key F - Spring Fade In End key G - Spring fading in duration

If the durations are prolonged, then the blending will be longer, and vice versa.
