Guest Tutorial: Simon Fiedler - Controlling Swirly Particles

Support us on Patreon: https://www.patreon.com/entagma 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.
