Where to find F-curve modifiers

For this exercise, we’ll animate everything in this scene using only F-curve modifiers. I wish I could say we didn’t need any keyframes at all, but we need some F-curves to work with if we are to modify them, and to create those F-curves, we need to insert at least one keyframe for each of them. On which frame? It doesn’t really matter! Once we create F-curves, the modifiers can take over and do the rest of the work.

Our first task is to animate the second hand of the clock, followed by its pendulum. When animated, these two objects will both rotate on the Y axis.

Let’s begin by creating the F-curves for that and accessing them:

1. Insert rotation keyframes for the objects Second Hand and Pendulum.
2. Bring up the F-curves for these objects in the Graph Editor.
3. Hide or delete all but the Y Euler Rotation F-curves.

Tip

You can insert keyframes for just one transform axis at a time by right-clicking...
