Join Ran Ben Avraham for an in-depth discussion in this video Expression linking the sphere’s rotation properties, part of After Effects: Bouncing Animated 3D Sphere.
- [Instructor] At this point,…I would like to start working on the spheres animation 3D.…Let's move to the main composition,…and we're dragging 3D sphere.…Now at the moment,…we are looking at the sphere's stretched pose,…so we'll move to one second down the timeline…to the normal pose,…just to help us see things a bit more clearly.…Let's apply to this sphere a slider control effect.…
We'll rename this slider X rotation. Wonderful.…Now let's duplicate it two times,…and we'll rename those Y and Z rotation.…So now we got a slider control to each rotation axis.…
Now, of course now we can move them back and forth…and that will have no impact on the 3D sphere, control Z.…To make sure that the sliders…do what they are supposed to do,…only to connect them with an expression.…To do that easily, all we need to do is…grab hold of the 3D sphere composition tab,…drag it and place it just beneath the viewpoint.…Now, we can see both compositions at the same time.…Now, in the 3D sphere composition,…we'll mark it the texture map,…
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.
