Understanding joint selection handles

Once the model deforms with the skeleton, joint selection handles can be added for the animator to control the rig and leave the skeleton intact.


00:03

The model now deforms with the skeleton,

00:06

which is great because it will allow us to visualize how the

00:09

controls are affecting the joints as we build the control rig.

00:14

Ideally, we don't want the animator to be able to touch this skeleton. Though

00:18

instead we need a layer of controls on top of this which will drive the joints

00:24

with that said

00:25

we also want to avoid driving this skeleton directly or adding other nodes into its

00:30

hierarchy as this will cause issues when it comes to export to the Unreal engine.

00:37

So we want to leave this as it is.

00:41

So what options are available to us? With regards to controls?

00:47

The most basic option available is to simply use selection handles

00:51

to show these just select a joint and go to display

00:55

transform display

00:57

selection handles.

00:60

You can also show them through the attribute editor.

01:06

Just go down to the display tab and check display handle here.

01:13

Now you may not have noticed it appear because it's in the

01:15

same place as the joint which makes it difficult to see.

01:19

We can however move the handle into a more visible place,

01:24

switch to component mode, either using the button or just press F eight

01:30

and select the handle option here.

01:33

This lets you select and move the handle. So it's easier to see and select

01:40

so we can use that now to select the joint.

01:44

I realize I said at the start that we don't want to edit this skeleton directly.

01:48

This is just a demonstration

01:51

but you may have other joints driving this skeleton

01:54

which you could use the display handles on.

01:57

It's good to point out though that you can use display handles on other nodes,

02:01

not just joints.

02:04

Now, there are a few problems when it comes to display handles.

02:08

Firstly, if I decide I don't want to show the joints,

02:13

the handles become hidden too.

02:18

The same happens if I hide the joints manually,

02:21

so they are pretty useless for us at this stage.

02:25

Another issue is when you have a lot of them on screen at once.

02:29

This can make animation confusing because the animator

02:32

doesn't know which handle controls which joint.

02:36

So that selection handles.
