Making the rig scalable

00:04

We have all the main controls in and working now.

00:06

But before we lock this down and add in the finishing touches,

00:10

we need to make sure the rig is scalable.

00:13

This may seem like it's a bit of a waste of time.

00:15

I mean, why would anybody want to scale this character?

00:19

Well, it's useful in a number of instances.

00:22

It could be that the scenes scale has changed.

00:25

So the character needs adjusting or perhaps the

00:28

character needs to change scale in the game.

00:31

It could be that you're using the same rig on a number of different characters

00:36

and you want to vary their scales as well.

00:39

So it is quite useful and it's become a fundamental part of rigging. So it is expected

00:44

and it's not difficult to set up. So it will make our rig even more powerful.

00:51

So when I talk about making the rig scalable, I mean,

00:54

being able to select the root control and scale it like this.

00:59

So as you can see, we have some issues to iron out

01:03

the character is deforming and changing shape,

01:05

but we need him to maintain the same proportions.

01:10

First, there are some basic things to check

01:13

open the connection editor

01:15

and to make sure the root control is in the left side,

01:20

we want the scale attributes here.

01:23

Basically everything underneath the root control is being scaled with it.

01:28

But the systems that are inside the do not touch group aren't

01:33

now,

01:33

we can't just scale the main group itself because some

01:36

of these systems already automatically scale with the controls.

01:41

So we will end up with a double transform.

01:44

If we adjust the skeleton group's scale though,

01:48

you see that we can get back to the correct scale.

01:52

So we know we need to connect this to the root control. So it scales with it,

01:56

load the skeleton group into the right side

02:00

and connect scale to scale

02:03

the character. Now snaps to the correct scale, it's looking better already.

02:09

Now,

02:09

one thing to point out is that if you're

02:11

setting things to scale with the root control,

02:14

you ideally need them to have the same pivot point as the root control.

02:19

So everything scales from the same point.

02:22

Now this should be the only group you need to connect,

02:24

but it's always worth trying the others to make sure.
