Adding collision geo to our simulation

“

- [Voiceover] So now that we've created our wire simulation, we've added some different forces to it. We want to add one more element into the simulation. And that's gonna be the core geometry that's at the center of our object here. If we go back into core build, we go under core, we can see we have this guy here. Click on the ROT guy. Basically what we wanna do, is we wanna add in this core geometry as a collision object. So the wires don't pass through that as they're moving around. Because right now the simulation it knows the root points of our wires. And so that's helping us have our procedural animation drive the wire movement and keep those in place. But the simulation doesn't know that there's this piece of geometry in the center and so we could hit a point where those wires just started passing through that thing, depending on their motion in the scene. And so we just want to set this up as a collision object. And obviously this could be anything. We could have all kinds of…
