View Full Version : using spline ik but maintaining bind pose

01 January 2008, 03:58 PM
i was curious to know if anyone has any good workarounds when using spline ik for the inconsistency that occurs when you simplify the curve. i know that the nature of simplifying curves means that it might not be as precise because it has less cv's, but i feel like there has to be a way to keep the rig at its bind pose and still have a simplified curve. i could use less joints, but in this case i have a realistic spine that needs a joint for each vertebrae, and i don't want to deal with constraining 20+ clusters into a control rig. thanks!

you can try this one...

duplicate the spine apply splineIK to it with simplified curve... the joints will move slightly, then orientConstraint that spine to the original (bound) spline with maintainOffset... and you'll have it with spline IK and still at the bindPose

or you can do direct connections by adding plusMinusAverage node and subtracting the values that the joints have been rotated from adding the IK...
