I just started testing out what the newest build could do and i made a chain system. The one on the left is help in place with two constraints with the smaller cylinder rotating. The middle one has a free moving wheel hanging down. The final one is held in place below the rotating cylinder.
thats cool. I tried something similar. I had some trouble with a few of the links getting kinks. There is a tank tread thread over at continuum physics. have you tried using the chain as a tank tread?
No, i was just testing the constraints and compound bounding boxs.
