- [Instructor] Now we want to extract just the edge of our geometry from our simulated jellyfish body, for use in creating some tentacles. So if we middle mouse click on this body one, there's going to be a lot of stuff we see, one of which is this primitive extrude side group that was part of the original geometry that was modeled and created. There had been an Extrude node used, and we made sure to make some groups so we had access to that. So what I'm going to do here is I'm going to lay down a Blast node. Under my parameters, under group say, Extrude side. Display flag that Blast, and then go Delete Non Selected, and also do Delete Unused Groups. Awesome, so now I just have the edge of that geometry, which was exactly what I need. If I middle mouse click I also see I still have some other groups in here, and I've got all these attributes and quite frankly I don't really need any of this stuff right now. I just want my UVs on here, but we don't need anything else. So I'm going to…
