reverse joints chain direction along curve

[batarg]

I want to create two chains on one curve - one along and second in reversed direction is it possible?

currently ikSpline chain forces each child joints to distribute down the curve parameters. even if you invert joint's translate values.

I believe the curve direction dictates the direction of the curve. 

You could duplicate the curve, reverese it, and then use one to control the other with a wire deformer..

or use the same deformers to drive both curves

No deformers needed.  Just use the history stack.  Keep the reverCurve node around to take care of your reversed chain.

this is wise! thank you!

sadly, ikHandle accepts but doesn't understand shape data type connection that comes from create/outputCurve/outputGeometry... only worldSpace from shape...

ive ended up by mixing two ieads:

- use reverseCurve node with extra nurbsCurve under the same transform and making it intermediate
