- [Zach] In this video,
let's adjust the rig

so that it fits our new character.

So now we have the mesh
for our new character,

but now we need to adjust everything

that the rig will work properly.

First of all, let's select the rig,

go to the armature settings,

make sure that all layers are selected.

And for now, let's go back to
the octahedral display method.

And first of all,

we need to take care that

the joints are all at the right position.

So let's go to edit mode,

Have a look from the front,
make sure X symmetry is enabled.

Then let's select these bones
and place them somewhere here.

Now that the joint here
is at the right spot.

And let's select these here at the hand

and the fingers are at the right spot.

Then let's have a look down here,

I think this still is all fine.

We haven't changed the legs too much.

And up here we didn't change
the height of the head.

So this is all good.

Now I want to create a new
bone for the hat because I want

to be able to take the hat on and off.

For that, let's select this joint here.

Shift S, cursor to
selected, and then shift A,

to add a new, loose bone.

Scale it down,

press G, move it somewhere here
into the center of the hat.

Maybe move it a bit to the front.

Now let's rename this.

For that, let's simply select the hat,

press F2 with control C, copy the name,

and then here F2, control V, paste it,

and call it farmer hat.

So this bone is now loosely
floating around here.

Let's go to pose mode

and here we have to define some things.

First of all,

this should belong to
a certain bone group.

In this case, the secondary
bones assign this.

Then you can see this bone
is now applied to all layers.

You can add a bone when pressing M,

also with shift to multiple layers,

but in this case, it should only belong to

the second layer here where we
have all the secondary bones.

Now let's add a constraint.

We could, of course, just
parent this to the head,

but I want to be able to change
the parent, if I want to.

For example,

if the hand should take the
hat or something like this,

then we need to be able
to change the parent.

And that's why we add a
simple child of constraint.

Here we want to use the farmer rig,

and we want to use the
head bone as parent.

That means when I move the head,

then the hat bone here
will move along with this,

as you can see.

So now we adjusted the
rig from the proportions.

We added a new bone.

If we need, of course,

if you have some other
elements on your characters,

which should move independently,

then you might need to add more bones.

We added the child of constraint here.

However, and now if I click
on the character mesh,

go to the object data tab, vertex groups,

we can't find the vertex
group for the hat up here.

And that's why we have to
rejoin the mesh to the armature.

Simply select it then
with shift, the armature,

press control P and click
on with empty groups.

And then we should have the new

vertex group for the new added

bone down here, as you can see.

So, but before we assign the
hat to the hat vertex group,

let's select the armature here
and let's move it around to

see what's happening.

So in general, everything is
moving along, as you can see.

Except some parts of
the pants and the hat.

Let's check the head here,
everything moves correctly.

So of course attaching the loose parts

to the mesh is not a problem at all.

However, we have a bigger
problem when I move the face,

once here you can see that
some crazy stuff is going on.

So basically all the cubes I
duplicated or changed in any

way are now also deformed in a weird way,

with the shape keys.

And I think that's the case
because I adjusted the mesh

when I had selected that basis shape key

and the basis shape key now has all

the other information
with a new character,

but all the other shape keys still have

the old information from
the previous character.

However, there's a relatively
easy way to fix that.

First of all, let's go to edit mode,

here you can see it, actually.

When I click through the other shape keys,

this is what we have here.

And this is what the basis
shape key looks like.

Anyway, all we need to do now is

to select all the elements where we

had applied shape keys on,

which is the mouth, the
eyelids, and the eyebrows.

And also the head part,
this is a different story.

You can see that also the head is

doing something weird here.

So let's leave the head
out of the selection.

Then press control I to
invert the selection,

and press P and click on separate.

Now we have separated
all the elements where

we have shape keys on, which
are doing some wonky stuff.

And here on this new separated mesh,

let's simply remove all the shape keys.

Start with the bottom here

remove them and make sure
that the basis shape key is

the last one you remove.

So that the new shape here
is still stored in this mesh.

Now we basically removed all
the shape keys from all the

parts where they don't belong.

And now we can select this here,

then with shift, the other
mesh, and with control J,

we joined both.

And now if I go to pose mode here,

only the facial expressions
are moving around.

Of course, now we need
to adjust them a bit.

Let's go to edit mode of the
mesh here and let's click

through them and see what we can do.

X symmetry is still enabled,
let's de-select everything.

And let's adjust the shape here a bit,

also from the beard when the
mouth is doing some stuff.

So it's going a bit to the inside when

he's doing the o mouth,
happy mouth as well.

This should move up a bit.

Something like this, sad mouth as well.

Let's go down a bit.

Press double G, and C to
extend this here a bit.

Then open mouth, this is mostly important.

Let's select the entire lower beard here,

press G Z, move it down,
something like this.

Then let's move this down
and this here as well.

And these two here as well.

So, and for the eyes, we
don't need to change anything.

This looks all good now,

and now when I select the face
bones and move them around,

you can see everything
works now as it should.

So the last thing that is left here is to,

reconnect all the parts to
the correct vertex groups.

So as you remember,
when I moved this here,

you can see that some
parts will stay in place.

So let's go to the mesh here.

Then let's go to the material
and click on farmer hat,

click on select and farmer hat to select.

So the materials can be used
to quickly select different

parts of the mesh, which is pretty cool.

Then go to the object
data tab, vertex groups,

and here we can find the
hat and then hit assign.

That means here,

the hat bone is now moving
their hat around so we can make

it wiggle in the wind and stuff like this.

Then let's select these parts here and

they should be applied to the chest.

Assign.

And then we have this cube thing here,

which should be assigned to the belly top.

Assign.

That means now when I'm not mistaking,

everything should move along correctly.

And we can take the hat off and

put it in the hands, for example.

And then all we need to do
is to change the child of

by putting this into hand R, set inverse,

and now the hat will
move along with the hand.

Pretty cool.

So let's undo this and the
hat should be on the head

hat and head sounds pretty similar.

Yeah!

And then let's go back to the
wire display for the bones and

let's disable all the helper
bones here, and voila!

We are done creating a completely
different character out of

our base character.

Pretty cool.

And yeah, when you have created

a different character than I,

I would love to see your,

rigged new character down
below in the comment section.

So please share a screenshot
or a render of the character.

And I just showed you a how
to attach the hat to the hand.

But in the next video,

I will show you how you can
attach something else to the

hands of this character.

But before we do that, as always,

don't forget to save...oh,

stop! Don't go!

I just noticed, I forgot
one thing down there.

You can see the one side of the boots

is doing some wonky stuff here.

This part, make sure this is selected.

Then click on this arrow
here in the vertex groups and

click on remove from all groups.

So it will be removed from any
other vertex group where it

doesn't belong,

and then search for leg bottom R, assign,

and then this should be correct.

Yeah, this looks better.

All right,

and that's now really
it, so yeah, just save.
