All language subtitles for 07_06_character_rig_deform_bones

- [Zach] In this video, let's
start the rigging process

of our cubic worlds character

by adding the deformation bones.

The defamation bones
are actually the bones

that will later on deform
the mesh we have here.

And besides the defamation bones,

we also have the controller bones,

which we need to control the rig later on.

And these will not deform
the mesh in any way.

First of all, I wouldn't
recommend to use any

of these two characters here,

because they are already rigged.

Instead, please use one of the two files

which are attached to this lesson here,

or use the cubic world
version of yourself,

which you maybe have created
in one of the last lessons.

So first of all, make sure
that the 3D cursor is down here

in the center, if not hit shift C.

And of course the character
should also be perfectly

in the center here.

And I would also recommend
to put the origin

of the character down here and
to place the armature object

at the exact same spot here.

So let's hit shift A and
add the armature object.

First of all, with the armature selected,

go to the armature settings over here,

view port display, and enable in front.

Then this bone will
always be shown in front,

as you can see, no matter
if it's inside an object

or behind an object.

And what I also do, I enable names,

then we can see the names
of the individual bones here

because when rigging, naming
the bones is very important

as you will see later on.

So before we go into edit mode,

let's rename the armature into rig male,

something like this.

We have the character male,
which is the mesh object.

And then we have the armature object here.

Let's switch to edit mode
and to make working here

a bit easier, let's press
T and enable the move tool,

so we can see this little gizmo here.

So, and first of all,
let's start with the bones

which are here directly in the center.

So the hips, the belly, the
chest, the neck, and the head.

And for that, let's move
this bone up here to the top.

And as you can see, the shape of the bone

is now filling out the
entire character here.

To be able to see through the
bone here, let's enable x-ray.

So then let's move the root
down here to the position

of the hips, somewhere here.

And the top part should be
somewhere at the top of the head.

And it doesn't really matter if a bone

is like exactly inside or
slightly outside an object,

because later on we just
manually define which vertices

of the mesh should move
along with a certain bone.

Now let's separate this
bone into multiple parts.

All in all I want to have six
bones now, one for the hips,

two for the belly, one for the chest,

one for the neck, and one for the head.

So let's select the bone, right-click,

and click on subdivide.

And then down here let's
increase this to five cuts.

Then we should have six bones.

And now first of all from
the front view let's adjust

the position of the joints,

so this here is around the belt
area and here we just orient

ourselves on the cubes
here in the background.

So let's move this here.

This somewhere here.

This down here, and
this up here is correct.

And from the side view
let's adjust this as well.

Maybe let's move these two
here a bit to the front,

so it's more at the
center of the legs here.

And this one here let's
move to the front as well.

This one should be at the center.

Let's undo this and grab the head as well

and move this roughly in the center.

And don't worry if you
will later on realize

that the position of one
of these bones is not

at the exact spot where the
certain thing should rotate.

Don't worry, we can always
go back to edit mode

and adjust the position
of the bones later on.

We will rename them in a second.

For now let's continue
with adding the bones.

And for adding the bones at the
arm let's go to object mode,

select the mesh, go to edit mode,

and with x-ray still enabled,
let's select this face here,

hit shift S and hold down shift S,

and go to cursor to selected.

Then the 3D cursor jumps over here.

And by the way, if you
can't see the 3D cursor,

you can enable this over here.

And you can find the snap
option also under mesh, snap,

and then cursor to selected,

and also all the other options.

Then let's switch back to object mode,

here select the armature,
go back to edit mode,

and now you can see the
3D cursor is still here.

Let's hit shift A to add a brand new bone,

and this we now want to place
somewhere here in the elbow.

Of course we could just like eyeball it,

but we can also do the same trick again,

let's select one of these faces here.

Maybe even both of them
here from both cubes.

Shift S, cursor to selected,

then it's here directly
at the elbow position.

And then let's select this
one here of the armature

in edit mode, shift S,
selection to cursor.

And here again, as you can
see, the arm is bended a bit,

which is really important,
so that later on

when using all the
controllers and constraints,

this arm will bend into
the right direction.

So it's important that for
the legs and for the arms,

there's a tiny bit of bending involved.

So let's extrude this here
and let's do the same trick

one more time, let's select
this here or this one here,

or maybe both, snap the 3D cursor,

and then let's put this over there.

You can see that the roll of these bones,

their rotation is pretty wonky right now,

but we don't care at this point.

We will adjust this a bit later

because it is indeed important.

Then for the hand, maybe
let's move this up a tiny bit

and then extrude this,

and here let's lock this along the X axis,

because for the hand and
feets it's recommended

to have them perfectly straight,

which makes animating
them later on easier.

Because when you, for example,
move this along the Z axis,

it will move perfectly up and down.

Then let's extrude this here,
here let's quickly eyeball it.

Let's have a look from the top view.

Maybe move these two over a bit, yeah.

And for the thumb,

let's do the snapping trick one more time.

Snap the cursor,

then in the armature object
in edit mode, hit shift A,

add a new bone,

and then let's snap the
tip up here to the cursor,

shift S, selection to cursor.

Now what's left here are the legs.

And by the way, as you can see,

all the bones which are like
mirrored to the other side,

I will now only create on one side

and then later one we'll
mirror them to the other side,

which will save us a lot of time.

And even the renaming will be
done automatically later on.

So for the legs let's go in here,

grab this face, shift
S, cursor to selected,

and then shift A, add a new
bone, move it down here,

and then let's do the same thing again.

Something like this, extrude here,

I would just roughly extrude
down because I want to bend

the leg again a little bit.

Move this one to the front
a bit so that we also define

the direction in which
the leg should be bent.

This doesn't have to be extreme like this,

but just a tiny bending.

Here we have the ankle,
which is pretty much

on top of the feet down
here, move it a bit down,

and instead of going down like this,

we will similar as for the hands,

move it straight to the front.

And here it doesn't really
matter that the bone

is not inside the mesh
because the position of a bone

is not really important
in terms of if a mesh

can be connected to a bone.

The position of the bone is
only important for placing

the joints at the right spot
so that the mesh later on

can rotate and bend in the correct way.

Now we have all the important bones,

which we will use to
deform the mesh later on.

Of course not for the other side,

but we will mirror this as mentioned,

and now let's rename this.

So let's start with the hips here.

Let's press F2, and I will
always use the rig male name

in front of each bone,
because if we later on

add multiple characters to our scene,

then it's good that each
bone has the kind of name

of the rig it belongs to,

so we better can distinguish
what bone belongs

to which character.

So this one is rig male hips.

This one I call belly bot, and by the way,

I add these underscores here,

which is just something I got used to,

but you can also use space
or dots or whatever you like.

So there is no right or wrong here.

Just do it in a way that you know

on which position the bone is in the rig.

This one I call belly top.

This one is the chest.

This one the neck and
this the head of course.

And now very important
for these bones here,

we need to define that
they are on a certain side

because when later on we
mirror this to the other side,

we need to distinguish
if it's the upper arm

on the left or the right side.

And in this case this
here is the left side.

From our view it's of
course the right side,

but from the view of the
character, it's his left side,

here the left arm and the left leg.

So let's call this one here, arm top L.

So you can use an L, you
can use left or right,

the full word.

And later on, when we mirror all the bones

to the other side, it will be renamed

into R or right automatically,
which is pretty cool.

This one here is arm bot for bottom.

This one here is hand fingers.

And this one is the thumb.

Then we have the leg top L,
the leg bot L for bottom,

and we have the foot L.

So now all the bones
are renamed correctly,

and the mirroring to the
other side happens later

when we edit all the
constraints and so on.

Of course you could do it right now,

but then you have to
manually add constraints

and all this stuff to
each bone of both sides.

So mirroring the whole stuff
later saves us a lot of time.

So these are now all the
bones which will deform

the character later on.

And in the next video let's add the bones

to control the character.

And of course, as always,
don't forget to save.
