Setting the scale for the torso

00:04

If you remember,

00:05

we needed to use different nodes to calculate the scale and distance

00:09

and these are being offset because of the overall scale.

00:13

So we need to add the scale values back into them

00:16

to correct that offset.

00:19

Let's jump into the node editor

00:21

and move it

00:23

here. We have the spine stretch systems

00:26

so we can quickly insert a new node here to help with the scale.

00:31

What we need to adjust is the scale factor nodes values.

00:35

In particular the curve length value here

00:38

as the rig scales, the curve is getting longer,

00:41

but this value represents the curve at its default scale.

00:46

So this needs to adjust as the rig scales.

00:49

What we want is the curve length to multiply by the root control scale.

00:54

So this will then give us the correct value.

00:57

Let's duplicate the scale factor node

01:01

and rename it to spine global scale.

01:05

We have the base curve length here. So let's copy this and put it into input one X.

01:13

We also need to change the operation to multiply.

01:17

So this will multiply input one by input two.

01:22

Let's open the connection editor

01:24

and load the global scale node into the right side,

01:29

we need the input two X attribute

01:32

now because this is a single attribute, we can't use a scale attribute.

01:36

Instead we need to choose one

01:39

because the height is usually associated with scaling,

01:42

connect scale Y to input two X.

01:47

So this is now multiplying the base length by the roots scale of 1.24.

01:53

Let's connect this to the scale factor node. Now

01:57

I'll just open it.

01:59

This is the value we want to replace.

02:01

So connect output X

02:03

to input two X

02:05

and the torso snaps back into shape because it's now

02:08

using the correct curve length to determine its length.

02:13

If we scale the rig, the torso seems like it's fixed. Now.
