I am trying to get a chain to animate correctly around 2 gears. I have tried a few different things. The two best setups I have had: I created to circular animations, and one per gear and then two lines both containing pieces of the gear that would operate at the same speed as the gear animation. I did not like this one because I need to make the gear pieces snap or jump back to their original position. They were only moving a short distance, but the over all effect worked, sorta.
The other setup I have is with singular rotation with an offset pivit and the end result is run through a lattice to give the propper shape, but my density at the squashed ends is certainly far from what I need it at.

I don't think I have yet approached it correctly. I am just looking for some other suggestions.
Thank you
