Thank you for helping me get to this point. It might be worth adding some of the functionality ive been using into obi in the future. Im happy to give you the script of this if you wish. The one i wrote for you is slightly wrong (for loop i should start at 1).
The script ive written is a bit messy, but it does a little bit more than just allow rods to be animated. It also generates a rod based on a joint chain automatically having been given the root of that chain, then links all of the joints to follow the particles of the rod. (so you can use a skinned object, like a character's tail) And then with this part, you can animate the physics of that tail if you select the root joint of another chain to copy. Would you like it?
