I didn’t think I would ever have rigged models in my archive, but when I set out to rebuild Mathias Hahn’s wonderful Scantling Lamp for Marset in Max, I just could not bear the thought of having to pose it by fiddling with its three axes and its pesky wires.
The solution: a simple IK chain (see viewport grab below) that will let you do pretty much all the lamp can do in real life just by moving a small dummy around. The wires are controlled by two additional spline IK chains so that they stick to the lamp as it moves (the wires may need some hand-tweaking to avoid interpenetration). All axes include angle limits to make sure you don’t break the lamp by twisting it around.
The rig is not particularly sophisticated but although it was conceived to allow for easy posing, it might be just good enough to be used for animations (in case anyone wants to emulate the Pixar ident).
