All language subtitles for 06 - Add details with Boolean

- [Instructor] One handy modifier that we should cover

is the Boolean modifier.

Let me show you.

If you're not already in object mode,

go into object mode

and let's go ahead and add a new 3D mesh.

In this case, I'll go ahead and add a UV sphere,

click on UV sphere,

and I'm going to drop these segments down to say eight.

And down here under rings, let's go to four.

There we go. That looks pretty good.

Go ahead and drop that down here.

I'm going to move this somewhere back here.

I don't want to move it on the X though,

just kind of back here and let's scale it in just a tad.

Finally, move it up.

Now let's go ahead and Boolean.

With my spaceship here,

I'm going to left-click on it and go to add modifier

and I'm going to go to generate Boolean.

Let's open this up a little bit to get some real estate.

Scroll down and you'll see I have a few options,

but notably a little eyedropper right here.

I'm going to click on it and hover over my sphere.

Now, I can actually come up to my outliner

and turn off the sphere's visibility.

And look at what happened.

I've cut a hole right into my mesh.

That's because I'm using difference.

I could also use intersect

and just get the data of these two areas

where they intersect.

I can go to union where I bring them together.

Or again, right back down to difference.

And you might be asking, why is there a hole?

It's actually at the bottom of this mesh

I realize that there is a hole,

and that's a common problem with Booleans.

If you have a hole anywhere else,

it will make a hole for you.

So let's go ahead and actually go to vertices mode,

inside of edit mode of the spaceship

and I just want to drag these vertices

and just drag them to the right.

Because I have clipping and merge on,

I can't go any further than zero zero.

And let's come up here to the top and you'll see

that there's the tiniest little hole here too.

So what we want to do is left click

and hold down Shift and drag a little box.

Shove these over.

You know, for good measure,

let's just check some of these others out

and make sure that we can make this

as watertight as possible.

That's a phrase that you'll hear often.

That basically indicates having no holes in the mesh.

All right.

Now I'm going to go back into object mode.

And look at that, instead of cutting out a hole,

it actually carved out like a chunk.

I can come back up here

and turn the visibility of my sphere on,

but of course it's going to be a little hard to see

what I'm carving out.

So I like to click on this little object properties

and scroll down a little bit.

And where it says visibility, viewport display,

there it is, display as bounds.

You could also display as wire if you want,

whichever you'd like.

Now I can move up the sphere

and see how it carves it out in real time.

The Boolean modifier is a really, really handy modifier

'cause it allows you to quickly merge

a bunch of different shapes into your object.

But beware if there's any hole

and if it's not watertight,

your Boolean will also rip out a hole.

But if it is watertight,

it's going to make this nice little carving.

You could use this to say,

carve out a new engine at the back

or add like a little area for say a cockpit.

So go ahead and play with Boolean

and see what interesting shapes you can add

to your newfound spaceship.
