Setting Rest Positions for Curve Chains
Every deformation rig needs to have a set resting position. The resting position is important as it acts as a 0 point for all the transformations that will be made to the drawing when animating. The resting position is also where we can see what parts of the drawing are assigned to which curve.
- In the
Node orTimeline view, select the deformation group ornodes containing the deformation chainyou want to set.
- In the Deformation toolbar, click the Show Selected Deformers and Hide All Others button to display the deformer controls in the Camera view. This also hides all the deformer controls that were displayed.
- In the Deformation toolbar, click the Rigging tool.
The chain turns from green to red. A green chain indicates the puppet is in animation mode. A red chain indicates the puppet is in a resting position. Make sure your chain is red.
- In the Camera view, setup the deformation chain.
- Use the Pivot rotation handle to change the angle of the chain.
- Use the Pivot centre control point to reposition the entire chain.
- Use the curve handles to modify the shape of the curve.
- Use the curve’s square control points to resize and reposition each segment of the curve chain.
- Repeat until all the curves of the chain are correctly aligned to the element to which it is linked. You can also set additional parameters in the Layer Properties window
—see Deformation Nodes.
- With the deformation nodes
or groupstill selected, in the Deformation toolbar, click the Reset Current Keyframe button. This will set the current resting position as the current frame one.
- Test your modifications using the Transform tool.
