Animating Luxo Jr.

Rigging and animation of the Luxo Jr. lamp, IK constraint management, composition, and lighting. An overview of the challenges encountered and the solutions found

I completed the 8.5-hour tutorial from Omnis School, recreating Pixar’s first animated film, Luxo Jr. The last parts covered rigging and animating the elements.

I must have made quite a few mistakes in my modeling, because the rigging turned out to be quite difficult, and it shows in the final rendering. For the ball, I used an empty to move the ball and the Transformation constraint to automate the ball’s rotation based on its position in the scene. In order to animate the lamp’s body from a single bone, the video recommended using the Inverse Kinematics constraint, and it worked pretty well, except that I couldn’t assign a Pole Target without completely destroying the main character. In any case, not wanting to spend much more time on this tutorial (which I started over a week ago), I was able to achieve the movements as best I could, with very unconvincing jumps and springs that behave strangely, not to mention the light and the image. It can also be observed that the lamp’s base often extends beyond the balloon or the ground.

The next day, I was able to refine everything, especially the lighting, add a bit of smoke, and do the compositing, for a much more satisfying result, even if the animation is far from perfect, and there are some glitches that I don’t understand.

Great tutorial, I was able to learn about rigging, animation, and the compositing tab, and I think I’ll continue with this theme, perhaps a more chill and shorter modeling video first.
