IK Spline Issues

Hi

I have been creating a rig for a doll styled character I modeled.

I have rigged the legs, applied an ik handle (note: This character doesn't have traditional feet so I didn't need to design a reverse foot chain.) on them and currently working on a control object for the legs.

The issue that I have is with the IK spline that I am currently building, I used the CV Curve Tool > Curve Degrees set to 1 Linear. Once I had finished re-positioning the curve so it fitted my model I then used the Rebuild Curve Tool to that it would evenal place a total of 6 CV's and then I ran a MEL script that creates a joint on each selected CV. With the six joints (to be bound to the model), I duplicated them scaled them down a little and then renamed them as joint drivers. I parented the joint drivers so that the chain was going from A (at the bottom) working its way up to F (the neck line).

I use the IK spline tool Animation > Skeleton > IK Spline Handle Tool (options) > I turned off the Auto create curve, also I turned off the Auto Parent Curve. Then with the IK spline handle I select the joint driver A, Ctrl click Joint driver F and finally Ctrl click the cSpl spin01 curve. Here is when I come to my problem, when I apply the IK Spline Handle the order of my parented joints Drivers flips, so A becomes where the neck is and F is where at the bottom of the model.

Any help and suggestions will be much appreciated.

Thanks

You've drawn your initial spline curve in the reverse direction. Just go into component mode, select all the control vertices and rotate the chain 180 degrees on the Z axis.
