POP Wind: Down

“

- [Instructor] Now we're gonna start adding some different pop nodes, start controlling the motion of our particles. And first off, actually I'm gonna delete out the default gravity in the scene it was good to see just sorta the initial result of that but we actually, we're gonna control how the particles move in the scene, via pop nodes and not via this gravity dot nodes, so I'll get rid of that. And now under our particles source node, I'm gonna make a pop wind. And we're gonna have two of these doing different things. So I'm gonna call this one pop wind down. And with that selected, we'll open up the parameters and this is what we wanna do, I wanna have the wind velocity actually be negative 30 on the Y. And then what we're gonna do is I'm gonna turn on the vexpression so the overall wind area up here and I'm gonna have an expression that fades this up over the life of the particles. So when the particle is born this negative 30 wind velocity isn't applied but over the particle's…
