Example of an animal shaking
The following example illustrates how you can
make fur react to the motion of the object it’s attached to. For
example, when an animal shakes its body, its fur reacts to the motion.
For simplicity, we’ve used a cylinder to represent the body of the
animal.

To make fur react to motion
- Make a cylinder and add lights to your
scene.
