Some examples of how to use the spring modifier in v2.

Creating springs

The first modifier in the image below makes springs (yellow) between fragments that were inside a volume in their initial position (at the start frame).

The second modifier finds the fragments within a different volume, then makes the *existing* springs (red) between them stronger. This does NOT create new springs, it just modifies the existing ones.

Destroying springs

The event has a volume filter to isolate the green fragments. The modifier destroys springs that connect fragments inside the volume to fragments outside the volume, i.e. between fragments which are modified by the event and those which are NOT modified.

This causes a chunk (green) to fall out, but keeps the springs between fragments within the chunk, only removing the ones connecting the chunk to the rest of the fragments (blue).

Detach velocity

The pink springs connect the fragments to a passive input object.

The yellow springs connect the fragments to each other, as soon as they’re created (when the cube is broken).

The last modifier finds fragments in the volume (the lower half) and edits the detach velocity of the springs connecting them to anything outside the volume. This weakens the link between fragments inside and outside the volume. The lower half is more likely to detach when it’s hit by the ball. (All the blue springs have detached and so don’t appear in the image.)
