I have a sphere that has been set to follow a nurbs path.

At the same time, I'd like that sphere to follow another path that happens to be a circle, and that circle moves along the nurbs path too.

For some reason, when I add two contraints to the sphere, it follows the path but it won't follow the circle too, meaning it won't loop in a circle.

How can I possibly do that? Here's a picture:

It moves smoothly along the path, but the ball won't follow the circle.

How would you go about animating the same object twice?

  • $\begingroup$ You cannot follow two path. What you can do, is parent them… $\endgroup$

    $\begingroup$ Have the circle follow the nurbs path and the object follow the circle. $\endgroup$

If you want an object to follow a path and that path to follow another path, the simplest approach is to do precisely that. In your case, a sphere is to follow a Bezier Circle that is to follow a Nurbs curve.

  • Make sure that all three have scale applied.
  • Select the Bezier Circle and add a Follow Path constraint.
  • Set the target to the Nurbs curve and other settings as needed.
  • Select the Sphere and add a Follow Path constraint.
  • Set the target to the Bezier Circle and other settings as needed.
  • For each of the Bezier Circle and the Nurbs curve, set the Path Animation appropriately.

The Sphere:

Follow Path constraint for Sphere

The Bezier Curve

Follow Path constraint for Bezier Curve

The Bezier Curve's path animation settings:

Bezier Curve path animation settings

The Nurbs Curve's path animation settings:

Nurbs Curve path animation settings.

Resulting 100 frame run:

The resulting animation

Obviously You'll want to edit these things to suit your animation needs.
