You can add springs to a soft body’s particles to give the soft body internal structure and improve your deformation control. You can also add springs to regular particles to give them reactive, interconnected motion. The number of springs and their stiffness alters the effect of the springs.
You can create springs between particles and:
At least one of the endpoints of each spring must be a particle (or soft body particle). If one of the endpoints is not a particle, the spring does not affect the endpoint’s motion, but the endpoint’s motion affects the spring.
You can create springs on specific object components. For example, you can select a pair of particles from different objects and create springs on just those particles.
You can also create springs on emitted particles. This provides a cohesive mass of particles, for example, a gas cloud.
