The Springs module allows the use of different forces to generate different effects. Springs behave like "springs" that allow the particles to have a certain elasticity and generate more viscous fluids or even Slimes or SoftBodies.
Viscosity 2, Springs Force 0
Viscosity 2, Springs Force 15
Viscosity 2, Springs Force 25, Viscoelastic ON
Springs Force 100, Viscoelastic ON
We can see how having 15 force in Springs, the particles tend to stick together more, as if they had Springs. Let's see more examples.
Springs Force 100, Viscoelastic ON
Springs Force 100, Viscoelastic ON
As we can see, Springs and Viscoelastic allow a multitude of incredible effects to be generated.
