Add volume advection to wire sim

“

- Now that we've created our volumetric noise animation, we're going to take a look at how to bring that into our dynamic simulation and get all of this working together. So let me turn off that VEL volume, let's go back into our tentacle sim. Right off the bat, I'm going to add an SBD pin constraint node right under our wires object here for the tentacles. So we have some points in this geometry that are in a group called roots. And that's going to make sure that these points don't get affected by the simulation and stay locked to the edge of that jellyfish body. We do that with an SBD pin constraint and we open up the parameters. And under constraint points I'm going to type Roots. And that's because we had already put these points in that group ahead of time, this is just something you know to do. And that means that all these points that are now visualized with that icon are going to stay locked to their initial position coming in and then basically not get simulated. So I'm going…
