Editing foot FK controls

00:04

So we have just a few more areas to cover before this rig can be passed to an animator.

00:09

And one of the more important is the foot,

00:12

we could leave it as it is,

00:14

we can move the controls around and the foot will follow.

00:17

But it's a bit basic and doesn't give the animator a lot to work with.

00:22

Let's look at the FK controls first. As these are quite easy to set up

00:27

with these controls, we only want them to be visible when animating in FK.

00:32

But don't worry

00:33

once we're finished setting the foot up, they will automatically hide themselves.

00:37

What we want to do first is make them follow the FK foot control

00:42

to do this. We simply parent them to it.

00:44

Nothing complicated about that.

00:46

So we just move these to here

00:49

because we cleaned these controls earlier.

00:51

And by that, I mean,

00:52

move the values down to the offset parent matrix section in the attribute editor.

00:57

We now have values here because the controls parent has changed.

01:02

So this is a new offset.

01:04

So what we need to do is remove these new values

01:07

first, we need to reset the offset parent matrix section.

01:12

So right click and go to set matrix to identity.

01:16

Let's do that on the big tour too.

01:19

Now let's check where they are in world space.

01:22

So reset these values

01:25

and now let's move them out of the hierarchy

01:27

and reset the values again.

01:29

OK, good.

01:30

They are at the world origin,

01:32

which means they don't have an offset baked into them.

01:35

This could have been done using the freeze transformations tool.

01:40

Now, we have checked that

01:41

we can parent the toes back to the foot control

01:45

and now match the first control to the joint. It's going to drive.

01:49

So select the first big toe control

01:52

and

01:52

then the first big toe joint

01:55

and use the match transformations tool to snap the control to the joint.

02:00

Now do the same with the little toe,

02:02

snapping it to the little toe joint.

02:05

We can now reset or clean the values again.

02:08

So move them down here

02:11

or use the script.

02:13

OK. I'll just make sure the other controls are still aligned.

02:18

Yep. Good.

02:20

So we need to make sure we are working with the FK skeleton too.

02:24

So hide the IK thigh joint

02:26

and make sure the FK thigh is visible.

02:29

We don't want to control the wrong joints.

02:32

What we need to do now is clean the FK joints

02:36

so we can connect the controls to them directly.

02:39

So go through and move the values down.

02:43

Also remember to reset the joint orient values too to correct any movement

02:48

I'll go through and update the other tours now.

02:53

Ok. That's better.

02:55

Now, open the connection editor,

02:58

disable non-cable

03:01

and bring the big toe controls into the left side

03:05

and the joints into the right side

03:10

and simply connect the translate and rotate attributes.

03:16

We can move the joints. Now with the controls,

03:20

let's do the same with a little toe

03:24

just connecting those translate and rotate attributes to the joints.

03:33

Ok. So that's the FK foot controls in connected and working.

03:38

And if we switch to IK

03:41

they vanish.

03:42

Perfect,

03:44

told you it was quite a simple set up.
