This video shows how to use my MaxScript tool "Chain Rigger" for 3ds max.
This tool creates a simulation rig for a chain (free or constrained) with a few simple steps. The rig is an optimized one, very stable and fast to simulate, based on a reactor rope.
The scene used is an example scene, included with the script package which you can download from:
Like "Autumn Leaves", this tool is also based on a technique I used for some FX in Planet 51. Namely, rigging and simulating the alien-dog's chain.
