Animating Curve Deformers
Add keyframes and reposition the curve deformers to create animated sequences.
- In the Tools toolbar, select the Transform tool or press Shift + T.
- In the Tools toolbar, enable the Animate mode. This allows the Transform tool to affect the position and size of a layer at the current keyframe only, whereas it would otherwise affect the layer's position and size throughout the whole scene.
- In the Timeline view, collapse your character using the Expand/Collapse arrow.
- Select the first frame of the scene.
- To ensure your model doesn't disappear after 1 frame, extend its exposure by right-clicking on the first frame in the Timeline and selecting Extend Exposure or by pressing F5. In the Set Exposure dialog, type in the amount of frames in your scene and confirm. This will make your model exposed (visible) throughout your whole scene,
- Now, we will make your character's first pose. First, make sure there is a keyframe on the first frame of every layer of the model. This ensures that when you make the second pose later, your first pose will not be affected. To do this do one of the following:
- In the Timeline toolbar, click the Add Keyframe button.
- Right-click and select Add Keyframe.
- Press F6.
A keyframe is added on the current frame.
- Do one of the following:
- In the Timeline
or Nodeview, select the deformation group orany part of the deformation chain you want to display.
- In the Camera, Timeline
or Nodeview, select one of the drawing elements linked to the deformation chain you want to display.
- In the Deformation toolbar, click the Show Selected Deformation Chain and Hide All Others button.
The selected deformation controls appear in the Camera view and all the others are hidden.
- In the Camera view, do the following:
- Click on the centre of the deformation's root pivot and drag it around to reposition the entire limb.
- Use the pivot’s square handle to rotate the entire chain.
- Use the square control point located at the extremity of a bone to stretch or shorten its length.
- Use the curve handles to modify the shape of the curve.
- A point in an Curve deformation that's between two other points will have two bezier handles, one of each side. If you rotate one of the bezier handles, the opposite bezier will follow by default. If you wish to rotate one of the bezier handles independently from the other, do as follow:
- Select the handle you want to move independently from the other.
The handle’s colour turns white.
- Press and hold Alt.
- Rotate the handle.
- By default, transforming a point in a Curve deformation chain does not offset subsequent points. However, it is possible to offset a curve deformation point along with all its children:
- Select the point you want to transform
The point's colour turns white.
- Press and hold Ctrl (Windows/Linux) or ⌘ (Mac OS X).
- Either move the deformation point or rotate one of its handles. If you move the deformation point, subsequent points will be offset horizontally and vertically. If you rotate one of its handles, subsequent points will rotate around the deformation point.
