While a spline IK is really the way to go in this instance, you can get more control over how a normal IK bends by using a locator object and adding a Pole Vector constraint on it by first selecting the IK handle, then the locator and then pole vector constrain.
QUOTE(gmask @ 05/27/09, 09:40 PM) [snapback]308439[/snapback] you should probably use a spline ik.. then for each CV in the spline add a cluster and then parent each cluster to a locator or handle.
gmask, the spline works really fine but i could not parent to a locator how can do it?
