Hey @Fabio-B,

⚠ Please note that we cannot provide support for AI generated code. See Support Procedures: Scope of Support for details.

When you want the clones to move, or in other words to be animated over time, you will need a noise and cannot use hashes or random values, as they are not interpolated, i.e., continous.

"""Realizes an effector that attracts MoGraph particles spherically around its origin. Add the example to a Matrix object to understand its effect.
