Adding volume preservation to the arms

00:03

OK. So just like with the torso, let's also add in some volume preservation.

00:09

And this is exactly the same as we did with the spine.

00:13

Bring back the node editor.

00:15

If we look at the spine,

00:17

we have the volume multiply divide node here.

00:20

So let's just copy that

00:22

and open it

00:24

and move all these over

00:26

and rename it

00:29

because we copied it.

00:31

This node is already set up for us. So all we need to do is add the connections.

00:37

So

00:37

connect out color R from the stretch condition node

00:41

to the volume nodes. Input one X attribute.

00:45

Here we go

00:46

and output X goes to color two G.

00:50

Let's open the connection editor. So we can connect this to the joints.

00:55

So output G here

00:57

and load the buying joints into the right side

01:01

and connect output G to scale X and Z on each.

01:07

Now the arm gets thinner, the longer it is

01:11

again, we have some weights we need to adjust here,

01:14

but we can come back to those later.
