Ok, well i tried several ways to do this animation and nothing seems to work......

the curve is a U-shape like curve and the chain should go along the curve.......I can get the chain to go along the curve but not to deform to the curve......how do I do that?? I tried using tangent constraints and geometry constraints, that didn"t work.......
Then I put joints in the chain and skinned it, drew the curve made an IK Spline Handle and got the joints with the binded skin to attach and deform to the curve. Now my problem was animating it, I could make the deformation deform along the curve while it was moving up and down.

I have also tried using lattice and motion paths, but I couldn"t orient the chain to the curve with the right deformations......


can ANYONE help me?? I"m stuck......
any comment would help, thank you
