Reviewing the rig twist joints

00:03

So here you can see the follower joints we just built

00:07

and here they are for the opposite arm

00:11

down here, you can see them just outside each thigh

00:15

and they are controlling these twist joints in exactly the same way as with the arm

00:21

with the feet. We have the aim locator here.

00:25

What you need to remember with the feet

00:26

though is the orientation is slightly different.

00:29

We kept them in world space.

00:31

So when creating the aim constraint here, make sure maintain offset is enabled

00:37

or the foot will move to point towards the calf joint.

00:41

So we can pose the arm in I care like this

00:44

and the twist joints automatically adjust to the pose.

00:48

Again, at this stage, we can see the skin weights need another pass.

00:52

Now, we're getting a clearer picture of how the model needs to deform.

00:57

Let's switch the legs to FK.

01:00

So you can see we have the twist moving up here as the foot rotates

01:06

the same with the thigh.

01:07

The rotation is being passed to the twist joint here

01:12

with the like follow joints. They simply follow the cog joint

01:16

just like with our arm. Follow joints.

01:18

They followed the upper spine joint or the spine three joint.

01:22

Ok. That's the twist joints rigged.
