Another way to add complexity to a Mesh Model is to join multiple meshes together. Now, we can do that with this particular character, by joining his hand to his body. But before we do that, let me give you a little background on how this all works. So before we do anything, I'm just going to do a simple File>New, and this brings up a simple Cube. Now, I'm going to move this Cube out of the way. And we've done this before, where we actually take an object and we add a new one.
So I'm just going to add in a Mesh>UV Sphere, and this is basically pretty simple. We have two objects in the scene; we have the Cube and we have the Sphere. Now, something different happens when you're in Edit Mode. So I'm going to right-click on this Sphere, hit Tab to go into Edit Mode. Now I'm going to add in, using Shift+A, a Mesh, and I'm going to add in another UV Sphere. Now, when I do that, you'll see that, well, I get a Sphere here, but if you look over here in the Outliner, I only have one object.
If I hit Tab to go out of Edit Mode, notice how both of these objects are selected. In other words, they're actually the same object. So when I added the first Sphere in, in Object Mode, it came in as an object, but when I added in the second object in when I was in Edit Mode, it added in the faces and combined the two as one. Now, this can actually be quite handy, because if you just need some additional detail and you want it attached to the model, you can do it very quickly.
Now, if you want to do this after the fact, then you can also join them together externally. So if I select my Sphere and then Shift +Select my Cube, we can combine them. Now, this is important, the last object you select will be the master object, so in this case, the Cube is the last one selected, so the Sphere will go into the Cube. And we can join them by doing Object> Join, and the hot key for that is Ctrl+J.
And once we do that, notice how the original Sphere goes away and all we have now is a Cube object. And that contains all of those vertices. In other words, the detail from all of those objects goes into one. So now, if your brain has been going in fast forward, you can see how we can do this with the hand on our character. So I'm going to go ahead and just open up that file one more time, and let's go ahead and scroll in. Now, I've got basically a separate object here, and this is just a hand; I can hit Tab here so you can see how this is built.
Basically, I just took a Cube and extruded out a thumb. So he is going to have mitten hands, he is not going to have full fingers, but that's fine for this particular character. But what we want to do is just join this together. So I'm going to select my hand and then Shift+Select my character, whose name is still Cube, and then we're going to do Object>Join. And now, they're one object. And also notice how, because I still have the Mirror Modifier on them, that it actually mirrors the additional geometry, which is kind of cool.
So now, the next step is to actually go in, and stitch together this open space, and we'll do that in the next lesson.
