Configuring the arm scale

00:03

Let's now look at the arm,

00:05

we just need to add in the offset. So it adjusts the arm length value as the rig scales.

00:12

So let's go back to the node editor

00:14

and into the left arm tab.

00:17

Again, we already have the stretch systems here for us to use.

00:21

Where's the scale factor node here? You are hiding under the arm control.

00:26

OK? Duplicate the node,

00:29

open it

00:30

and rename it to arm left global scale.

00:35

Again, we have the base arm length value here.

00:39

So copy it to input one X above

00:42

and change the operation to multiply.

00:46

Let's go to the connection editor

00:49

and load the global scale node.

00:52

So we need the input two X attribute here

00:55

and load the root control into the left

00:60

and connect scale Y again to input two X

01:04

that's updated now.

01:06

So it will multiply the arm length by the rig scale which is currently 1.6.

01:12

Now, all we need to do is replace the input to X value in the scale factor node.

01:18

So connect output X to input two X.

01:22

Did you see the arm snapped back? It's now back at its natural scale.

01:27

So we com pose it

01:30

and if we scale the rig,

01:32

the arm stays in that purse and doesn't deform in a weird way.
