One of the more common ways to control a rig is by using nerves curves
00:08
and you could use something as simple as a circle.
00:12
This can then be attached to the joint. So when you move this, the joint follows,
00:18
this gets around the issue of controls being hidden when
00:21
the joints are because these are a separate element.
00:25
So this ensures the base skeleton can be tucked away and not touched by the animator.
00:31
You don't have to stick with a circle though
00:33
if you right click on it and select control vertex,
00:37
you can edit these points to reshape it to make it more unique.
00:43
This way you can have different controls for each area of
00:46
the rig making life so much easier for the animator.
00:51
What we can do is also change its color.
00:54
If we open the attribute editor
00:59
and go to the display tab,
01:02
we can enable the drawing over right
01:06
with these, we can change how you can interact with the control and how it looks.
01:12
If we change the display type to reference,
01:17
you see the control is now black,
01:19
this locks it so you can't select it,
01:21
which is useful for icons or labels
01:24
which are more for information than actual control
01:28
down here. We can update the color
01:31
when set to index. We can choose a predefined color from the top slider here.
01:37
So it's now green.
01:40
If you want more of a custom color, you can change this to R GB,
01:44
you can now choose a color from the bottom slider.
01:48
Let's go with maybe more of an olive color.
01:50
So that's the basic control using just a nerve circle. But it can be quite versatile.
01:58
There are more advanced options though available.
02:02
If you want a more custom control, you can use the curve tools
02:07
with the CV curve tool. We need to place four points
02:10
and then a curve is created between them
02:14
like this.
02:16
It looks a little rough but we can press three to smooth it out.
02:21
The edit point curve tool is probably the one I use the most.
02:26
Let's just move this over.
02:28
When we set the curve degree to one linear,
02:31
we can create more angular shapes.
02:34
So let's hold X to snap to the grid and create a simple arrow.
02:41
There we go
02:42
nice and easy
02:44
and we can just press enter to finish creating that curve.
02:50
Alternatively,
02:51
you can choose another option like three cubic to make softer curves.
02:59
You see as I place the points, the curve is created but its shape is much softer.
03:06
With all these curves, you can still go in and adjust them if needed.
03:11
With the pencil curve tool, you can simply draw any shape you want.
03:17
And the Bezzy Air curve tool gives you more control over the angles at each point.
03:23
If we create a basic angular shape,
03:27
we can go in and adjust the tangents
03:29
just like this.
03:31
So those are the main curve tools you can see how they
03:35
can allow you to create whatever shapes you need for your controls.
03:39
Alternatively,
03:40
you can also use a nerve sphere, which is more commonly used in facial rigs
03:46
but can like a more solid selection handle.
