[MUSIC] All right, welcome to our third sculpt. I hope you are feeling confident in sculpt. So what I want to do is go into a little detail about subdivisions and adding lines. So under the sculpt look I'll create a box, I'll drag it out. Great, as we talked earlier, I can subdivide within the tool, but you don't always know exactly how many subdivisions to add now. There will be times when you need to subdivide later in your development. So I'll say, OK. At any point in time I can take a line and offset it, a distance or I can take the face and subdivide it. Left to subdivide first under Modify. Come down to Subdivide and what the Subdivide does is take any face and split it into four sub faces. We'll say subdivide this face here. If you notice, what happened to my outer shape? See how the shape changes when I pick it? The reason it does that is you have two option for your insertion mode on the subdivide. The default is Simple, but you can also switch it to Exact. When it's set to Simple, the actual subdivision of that one face is job one, and it will only subdivide that face. But to do that, it has to adjust the shape to hold it. So if I switch it to Exact and I pick the same face watch what happens. It subdivides that face, but adds a lot more divisions. What that means is under Exact job one is holding the form, but to do that it needs to create many more subdivisions. So know the difference between Exact and Simple, and know the path you want to choose. So I'll say, OK. Keep in mind that if I don't want a line or subdivision, I can always click it and delete it as well. But keep in mind that every phase at this point in time is tangent to all of its neighbors. So if I get rid of this one here, I'm changing how these two relate to each other now, and how it relates to their neighbors and that will change the shape sligthly. So I can also grab both these edges and insert our new edge. So I'll say Insert Adge, I'll send it this way. If I change it to minus, it will go the other way. It's a percentage not a distance, it's half the distance to the next line. I could slide it, I'll leave the insertion mode at Simple and you'll notice that it changes the shape slightly, but that's okay for right now. So what happens if I garb these two lines and I move them up. Does the green center line move that's showing us our symmetry. Yes, it does and that's critical to understand. The next neighbor always move, so if that's not what I want I'll select these two lines, say Insert Edge, send that positive in the other direction, Say OK. So now when I move those same two lines again, does the centerline move? No, the neighbor on each side moves and creates a buffer. And I'll maybe rotate them in this direction as well, maybe a little higher, a little slide forward. And now I've added some muscular details in a very rapid manner. Subdividing and inserting edges are very important. I'd like you guys to spend some time practicing with both, practicing with Simple and Exact for each. I also want you to pick edges, delete them. If I delete all of these watch what happens, also what happens if I delete a face? What happens if I delete this face? What happens if I delete these three here? How does that affect the former shape? And what we'll do shortly is talk about what other things you can do with this opening? [MUSIC] [SOUND]
