POP Drag, Wind, and Color

“

- [Instructor] Next up, we're just gonna add a couple of nodes. So let's just shape our particle sims just a little bit. First off, I'm gonna do a POP Drag. And I'm gonna turn on Vexpressions, and I'm gonna type error resist multiply equals fit01. You'll see we've used these same expressions all over this course, these are really just common, standard, easy things. And we're gonna rand parentheses @id. I always add a little bit of randomness to that, 34.34, close parentheses, .01, .05, close parentheses, and finish it. Okay, and basically this is just creating a random number based on the id, and then fitting that between .01 and .05. Just adding a little bit of drag randomly to the different particles just to create even more organic variation. Next, I'm gonna do a POP wind. I'm gonna drag these guys down to give us some more room on our POP chain, here. So, open up POP wind. I'm just gonna change the amplitude to one on the noise just to add a little bit of noise into the system…
