Wobble operator

The Wobble operator allows you to simulate rotational springs on particles.

The Wobble operator works by coupling each particle with a new child particle in a 2-way relationship that has the following constraints: child particles will attempt to maintain their translational offset from their parent using a simple spring, and parent particles will adjust their orientation to continually look at their child along a specified axis.

Spring solver

  • X/Y/Z: the child offset axis.

  • Scale: the distance each child will be offset from its parent.

  • Stiffness: the stiffness of the spring.

  • Decay: the decay of the spring.

  • Variation %: the per-particle percentage of variation to apply.
  • Max force: the maximum length of the spring force vector.

Driver Particles

  • Delete if parent deleted: if a parent particle is deleted, the child particle will automatically be deleted.

  • Get shape from parent: controls whether child particles will inherit the shape mesh of their parent.

  • Inherit target link from parent: when disabled, target links between the parent particle and the parent particle’s target will not be inherited by child particles.


  • Show spring connections: controls whether a line will be drawn in the viewport connecting child parents with their parent.


  • Seed: the seed value for all varied parameters.
