View Full Version : Help with modelling of lamp Luxo Jr. in 3d Studio Max

I need a help in the modelling of famous lamp of Luxo Jr. from animated film of Pixar Studio (
All tutorials about inverse kinematics, which I found in Internet and in books, are applied to the simple (single, broken) chains of the linked objects. My case is more difficult: the kinematics chain of objects is closed (see attached picture 1,2:
I can not compel it to move correctly under animation. During the motion two parts of chain move not synchronously and disintegrate.
Whether it is possible here to apply only an inversion kinematics or it is needed to apply a skeleton from bones and attach all of details of lamp to the bones. May be someone has lessons on creation and animation of such models.
3ds Max 9 file with models of lamp is here:
It will be very beholden for a help.

Hello, gays!
See this wonderful tutorial ( or I also tried to do it in 3D Max. This is answer on my thread on this forum ( I already said good-bye to hope on an answer almost 3 months passed from the moment of placing of thread on a forum and not even one answer. I wouldn't manage with this rigged system. It is nowhere indicated in literature, that separate unlinked objects can be linked to the already existed systems of the linked objects. It was a basic problem which was decided by respected Shawn Hendriks from Autodesk.
Good luck!
