Flexing the tail (20/25)

Показать описание

Animate a rubber-hose style limb.

What you learned: Shape-Tweening an Art brush is a way to create flexible, noodly deformations of your designs.
* Isolate the visibility of the body and tail layers.
The tail’s bounce is complex, so animate that before aligning it to the motion of the body.
* There is more than one way to edit or reshape a line, or in this case, an art brush applied to a line.
* The line can be edited with the Direct Selection tool. Beware that repeated editing of a line with this tool may introduce additional control points, and degrade the shape of the line.
* Another way to edit the line is with the Subselection Tool. Along with the various Anchor Point tools, you can directly edit Bezier points and handles of a line without introducing additional points.
* Accessing the Anchor Point tools may need to be done through the Edit Toolbar panel, which is accessed by clicking on the three small dots at the bottom of the Toolbar.
* Creating an S-curve for the tail will require editing Bezier handles and the Convert Anchor Point Tool accessed as described above.
* Once you pose out the first position for the tail, convert the first, middle and last frames of the cycle to Keyframes to set this position as the starting point for the other Keyframes.
* Pose out the other frames of the cycle at the breakdown positions as determined by the timing used throughout your cycle.
* Add a Shape Tween to your Keyframes and playback to test the motion of the bounce. Make adjustments as needed.
* Once the bounce animation is set, go back and transform the Keyframes to register with the body’s position and twist.
* Make sure the layer order from near to far is correct.
* Save your incremental progress as a new file.
