Editing the Resting Positions for Bone and Game Bone Deformations

Every deformation point has a resting position. The resting position is important as it acts as the starting point for all the transformations that will be made to the drawing when animating. Using the Rigging tool, you can make adjustments to the resting positions of the point in a deformation chain.

How to make adjustments to a Bone or Game Bone deformation chain

Do one of the following:

In the Camera or Timeline view, select one of the drawing layers linked to the deformation chain you want to edit.
In the Timeline view, select any part of the deformation chain you want to edit.

In the Deformation toolbar, click the Show the Selected Deformation Chain and Hide All Others button.

The selected deformation controls appear in the Camera view. If other deformations were displayed, they are now hidden.

In the Deformation toolbar, click the Rigging tool.

The deformation chain turns from green to red. A green chain indicates that you're animating the deformation. A red chain indicates that you're modifying the rig.

In the Camera view, set up the deformation chain.

To rotate the a bone, click and drag on it. This will rotate the selected bone and all subsequent bones in the chain.

To offset the whole chain, click and drag on its root control point.

To reposition an articulation, click and drag on its control point.

To adjust an articulation's radius, click and drag on its radius control point. Make sure the radius of the articulation covers the articulation itself.

Repeat until all the articulations and bones of the chain are correctly aligned to the element to which it is linked.

Test your modifications using the Transform tool.

TIP When manipulating the articulation of a Bone or Game Bone deformer, you can press and hold the Alt key to lock the bone's angle and only shorten or elongate the bone. You can also hold the Ctrl (Windows/Linux) or ⌘ (macOS) key to break the articulation off its chain and make it into a new, separate deformation chain.

How to add an articulation to a Bone or Game Bone deformation chain

Do one of the following:

In the Camera or Timeline view, select one of the drawing layers linked to the deformation chain you want to edit.
In the Timeline view, select any part of the deformation chain you want to edit.

In the Deformation toolbar, click the Show the Selected Deformation Chain and Hide All Others button.

The selected deformation controls appear in the Camera view. If other deformations were displayed, they are now hidden.

In the Deformation toolbar, select the Rigging tool.

The deformation chain turns from green to red, meaning that you are editing the deformation chain rather than animating it.

Press and hold the Alt key.

While holding the Alt key, click on the bone where you want to add an articulation.
