The Inheritance Effector is probably one of the most underrated and underutilized effectors in the effector menu. In part two of my Inheritance Effector tutorial, I show you how you can fake particle movement that would normally only be able to be achieved with an Emitter or Thinking Particles and Xpresso. Using a combination of the Inheritance Effector and other Mograph Effectors and Deformers, you can achieve close to the same effect as an Emitter or Thinking Particles as a simpler alternative in your normal workflow without having to touch Xpresso.
Here is a spot where I utilized this technique:

Excellent Tutorial! Thanks!
Hey EJ – I’ve learned a lot from this tutorial.
Thank you!!
I think I’d mess up somewhere with TP and Xpresso nodes (’cause I’m just starting there),
but doing it this way is more of a “hands on” way – kinda.
