It finally happened – our dear friend Simon Fiedler (https://simonfiedler.de/) agreed to record a guest tutorial for us.

He decided to share one of his production tricks for controlling particles: Building a swirly vector field to advect particles. Although it looks organic and natural, it’s highly controllable using a few basic vector math hacks. Enjoy!
