With rigid and soft bodies, forces are the key to everything. They cause accelerations, deformations and changes of direction. “MultiJoints” MultiJoints are the same – forces are used to influence the links between interacting objects. These forces also affect the way a body behaves and moves, so they have an immediate impact on dynamic simulations. Joints can be seen as an invisible rubber band between bodies. Forces are used to determine the bands’ rigidity. This is something that is also displayed in the viewport during simulation. Under certain conditions, connected objects start separating from each other, and you can see the changing joints as lines made up of dashes with variable length. Higher forces give you more rigidity and the bodies can even glue together completely.

To give a simulation a more realistic appearance, it is often a good idea to randomize things a little. “@ Max force random” was introduced for exactly this purpose. The added variation ranges between 0 and the entered value. So, if this parameter is different from 0, you have to take it into consideration while adjusting “@ Max force”.
Apply force factor texture
When you press this button, you will see a node browser where you can choose an object. If the object has a greyscale texture applied, it can be used in combination with the currently selected MultiJoints as follows:
