This course provides an overview of modeling, animating, and rendering 3D graphics in the open-source software Blender 2.6. Beginning with a tour of the Blender interface, author George Maestri shows how to create and edit basic objects, work with modifiers and subdivision surfaces, and apply materials and textures. The course also demonstrates lighting 3D scenes, setting up and using cameras, animating objects, and assembling basic character rigs.
Another way to do organic modeling is to use Blender's Sculpt Tools. Now these are highly interactive, but they also require a little more density to the mesh. So I took this particular character, added a little density, and let's take a look at how to use the Sculpt Tool. Now the Sculpt Tool is actually its own mode. So if I right-click on this object to select it, you'll see that I have Edit Mode but we also have Sculpt Mode. And this allows us to actually sculpt the object.
Now as soon as this comes up, notice how my cursor changes to the circle which is basically a brush. All I have to do is left-click and drag on the object and you can see how I can sculpt the object. I'm going to hit Ctrl+Z to undo that and let's get a little more control over this. All of our options for sculpting are here in the Tools Panel or the Brush Panel. So I'm going to go ahead and open this up so we can take a look at it. Now we have a couple of options. One is the Radius of the brush.
I can make it smaller or bigger just by moving this option here. If I hit F, we can also change the Feather of the brush as well which is kind of nice. Then we also have an Autosmooth amount, we have Add and Subtract. So in this case, this will pull vertices out, add them, in this case it will subtract them, push them back in, and again, I'm going to undo that.
Now we also have what's called Symmetry. Now this can be very important particularly in things like character modeling. So I'm going to drop down here to the Symmetry Panel, roll that out, and open it up. And you can see, if we want we can actually have symmetry over any axis. And in this case, he is kind of sitting along the X axis, so I want my symmetry there. And when I do that, you can see how now when I start sculpting, it actually sculpts on both sides.
So if I change this to Add and maybe bring my brush size up just a little bit by hitting F, I can start to puff out this character's cheeks. And you can see how it's very easy to do that with the brush. Now we also have a number of different tools that we can use and let's go to that rollout. And we have the Draw Tool which is the default and this just allows us to basically draw on the character. But we also have a number of other ones, one is called Blob, Clay, Crease, Draw, which is what we're using.
One of the nicer ones is called Smooth, so let's take a look at that. And if you start modeling, you might get little bit of blobiness here but we can actually use the Smooth Brush to kind of put things back. Now another way to use that Smooth Brush is to get rid of Creases. So I'm going to hit F to go down a little bit. And if we want, we can paint over this hairline here and smooth out that crease and turn him from a guy with hair to a guy with no hair.
So if I want, I can increase my brush size and maybe smooth that out just a little bit more. And again, because I have Symmetry turned On, it's very easy to sculpt this character so that he comes out just fine. Now we have additional tools. Inflate is a great one that just pulls things out, it's very similar to Draw, but it's a little bit different. So if I go to the top of this character's head, you can see how I can basically inflate his head, give him a big giant brain or really whatever I want, turn him into a brainy alien or something like that.
Or if I want, I can turn this big mass now into hair and I can put that crease back. So I have a Crease Tool here, so if I hit the F key and shrink down my brush a little bit, I can start to put a crease in. But I've got the crease going the wrong way because I have Add On instead of Subtract. So I'm going to undo that, Ctrl+Z and hit my Subtract Tool and then just kind of paint in another crease.
And again, I can just paint in kind of a nice crease for where his hair is. So as you can see, this can be very, very handy. It's a really nice way to sculpt creatures, organic objects, really a lot of different things. So go ahead and start playing with all these tools, there is a lot of options here. I just wanted to kind of show you some of the basics of this to get you started, but you can go pretty deep into this if you want.
