Adding an envelope attribute parameter

00:04

What we can do now is use the envelope attribute here

00:07

to simply blend between the root controls,

00:09

orientations and the world space group's orientations.

00:14

The next step is to add this functionality into the rig.

00:17

So the animator can easily access it without having to find the blend matrix node

00:23

to do this. We can use the follow attribute. We add it to the upper arm FK control.

00:28

Although thinking about it,

00:30

it would make sense if this was a float instead of an enum.

00:34

So the animator can blend between the two states

00:36

rather than snapping from one to the other.

00:40

Let's add a new floor attribute,

00:42

call it world orient,

00:45

set the minimum to zero and maximum to one

00:48

matching the limits of the envelope attribute

00:52

and add that.

00:54

So we will use this instead

00:57

now connect world orient

00:60

over to the envelope attribute on the blend matrix node.

01:05

Let's also delete the follow attribute now too as it's no longer needed,

01:11

we can use this now or should I say the animator

01:14

can use this now to make the FK arm rotate locally.

01:18

So it follows a root control or stays in world space and follows the group.
