Join Ran Ben Avraham for an in-depth discussion in this video Connecting the sphere to a position null, part of After Effects: Bouncing Animated 3D Sphere.
- [Instructor] Our next step will be to connect the sphere…to a position null.…To do that, we'll first create a new null.…Control, alt, shift, Y.…We'll rename this null position and we'll make the filled…sphere a child of the null by clicking on the pinpoint…and drag it on top of the position.…We did this because we wanted to add the wiggle expression…to the position so that when the sphere isn't moving,…it won't stand perfectly still.…
Other than that, we want to add a second expression…that will add overshoot animation…to the position key frames.…To simplify this process, we separated the sphere's position…control to two separate layers: the sphere's own position…and a null object.…Each of those will hold one expression.…
This is a project-based learning experience. Each step of the process is rich with object lessons that are applicable to the variations that a motion design and compositing artist will face in the real world.
