Overview 

Soft body objects are simulated using a particle lattice in Lucid. As such, you need to apply the Lucid modifier to your object and set the body type to Soft. The mesh will be voxelized to generate internal particles and, using a set of settings you can adjust the behavior of the simulation.

Similarly, you can have a set of soft-body objects generated with Particle Flow geometry operator en masse.

 

Inflated 

A great way to simulate objects filled with air like tires, balloons, and bubbles is through inflated body type. This approach is faster than using soft-bodies because it only generates one particle per each vertex of the mesh. It also allows effects like tearing.

 

Soft body 

Soft body, like rigid body and fluid objects, generate a volume of particles inside the mesh. These particles are connected using soft constraints and act as a soft mass.

 

Troubleshooting 

 

Softbody object freezes or floats away 

  • Problem: Soft body objects either stay in place during simulation or start moving in a strange direction not respecting the forces within the scene
  • Cause: This can be caused by particles within the soft body overlapping each other or by the solver's inability to solve the constraints between soft body particles
  • Solution: Try to manually reduce the particle radius. Also try to increase the number of iterations within the simulation in Flex settings helper.
