Cinema 4D has a slice option on the cylinder primitive. In this video we will see how to use that with a Bool object to create a cutaway effect.
The effect is achieved by animating the slice’s From and To properties. By animating one or both of these, you can create a slice that grows out of nothing and rotates around a central point. The video below will show you how to leverage this in order to create a cutaway effect on a turbo-charger model.
