[Question] tank chains

Hello,

 I am trying to animate the chains of a tank. I have made a simple chain part and applied a bevel modifier, then an array, a curve modifier and assigned them to a nurb-circle which I have modified to fit my tank. Both the circle and part (As far as I know) has been created at the origin. I also tried to place the origin at the center of the volume and at the center of the surface for both the chain part and the nurb-circle.

Everything went as I would have expected it. So I proceeded with my experiment.

I then wanted to animate (and later rig all relevant part to facilitate the animation of my tank),

so I applied a < follow path > constraint to the chain part to automatically animate it. There is an undesired effect.

Please take a look at this effect in the file I have attached.

I really would like any feedback.

Thank you in advance.

    Macario,

    I'm not much at rigging and animation,  But I see something odd on your timeline at 5 seconds in the video.  Looks like jagged lines, then they straighten out.   Could you have keyed something offset movements there?

    assuming you mean "track" and not "chains", if you check on youtube there used to be a good tutorial by, iirc, Chris Kuhn, on how to rig/animate this.

    mac999 I think kkiller-wolf is referring to this course:

    Maybe you are actually already following it and struggling with a specific part of it ?
