Adding space swapping options

00:03

Let's add some space swapping options to these.

00:07

Let's also add some to the head and eye controls too.

00:11

Basically, space swapping allows part of the rig to follow another.

00:16

So for example,

00:18

with the eye controls we have here,

00:20

you can set these so they move with the head or remain in world space.

00:24

So they don't follow anything.

00:27

This is useful for keeping the eyes locked on to something

00:30

even though the rest of the body or the head is moving.

00:34

So as usual, we need a divider to separate this from the main attributes,

00:39

call this space divider

00:43

and call the first option space

00:47

and let's lock them.

00:50

I met them non cable.

00:53

Now that's added to all the selected controls,

00:56

we can deselect the head and eyes for now.

00:59

Next, we need another enum

01:01

call this follow

01:04

and use the following options,

01:06

world

01:08

cog,

01:10

hips

01:12

and clavicle.

01:15

So the control will essentially be told to follow one of these other controls.

01:20

So it acts like it's parented to them.

01:23

OK. Done.

01:25

So you will see that the arm control has

01:27

the option to also follow the clavicle control.

01:30

We also added this to the foot control too,

01:33

but we need to change this.

01:36

We don't want the foot to follow the clavicle control obviously.

01:40

Well, you might want to on your rig.

01:42

All we need to do is go to modify edit attribute so we can update it.

01:48

Let's change the last option to root instead.

01:53

So it will follow the leg's root control.

01:58

Now let's add some options for the head.

02:02

This time, we are going to use a float attribute.

02:04

So we can blend between the different states,

02:07

set the minimum and maximum values to zero and one

02:11

and call the first follow neck

02:16

and the second orient neck.

02:19

These will control how the head moves.

02:21

So the animator can essentially keep the head level as the body moves.

02:26

OK, on to the eyes now

02:30

and we are back to using an enum

02:33

set this to world

02:37

and then head.

02:39

So we want the eyes to either remain in world space or follow as the head moves.

02:45

We don't really need to add everything.

02:46

Now, we can always add more attributes as we build the rig.

02:51

Ah Yes, let's add some space swapping options to the FK limbs.

02:55

So let's select the first control on each limb

02:58

and add a space divider.

03:02

Now with the arms,

03:03

let's give the animator the option to stay in world

03:06

space or follow the clavicle like with the IK control

03:12

and the legs,

03:13

they can also stay in world space or follow the hips.

03:18

OK? So that's the main attributes added.

03:20

And like I said earlier, we can add more later if we need them

03:24

or we can easily remove them if we find that we don't.
