Updating neck and head controls

00:04

If I rotate the FK spine, now you see the neck control moves with it,

00:08

but it's staying halfway between the IK and FK controls.

00:13

This is because both weight values are set to one.

00:16

Let's update that. Now,

00:18

open the node editor

00:20

and bring the cog control in

00:22

and also remove the shape note.

00:26

Actually, if you don't need to see the shape nodes,

00:29

when you import things into the node editor, you can simply disable it up here,

00:34

just go to the display menu

00:36

and select no shapes.

00:38

Now it's gone.

00:40

And if we load the cog in again,

00:42

we're not getting those shape nodes.

00:45

OK?

00:45

We also need to bring in the reverse node which

00:48

we used earlier to control the IK and FK blending.

00:51

Let's graph this

00:54

and remove what we don't need.

00:58

OK.

00:58

Now we need the parent constraint node we added to the neck controls, offset group.

01:04

If you remember,

01:05

we connected the IKFK switch attribute directly to our FK controls and joints.

01:12

So let's connect it again. But this time to the spine three FK weight,

01:18

we used the reverse node to invert the IKFK switch value.

01:23

So the IK did the opposite of the FK

01:26

so we can use it again here and connect

01:29

its output X attribute to the shoulder control weight.

01:33

What we are doing is recycling the nodes

01:36

so we don't bloat the scene with systems that do the same thing.

01:41

You can see the weights up here.

01:43

The shoulder is now at zero whereas the spine FK

01:46

is set to one.

01:49

So the ne should now follow the FK controls.

01:53

Yeah, it is good.

01:55

We can use the IKFK switch attribute to blend the spine back to the IK controls

02:02

and the neck follows

02:04

it's now stuck to the shoulder control.

02:08

So that's the net control updated.
