![]() so I have a joint chain for a spine set up with an ik handle and three controls to drag the clusters controling the spline.
ive got a simple strech system set up, where ive created a curve info node using the arclen -ch1; command. in this case arclen is 141.789. I create a Multiply divide node,choose divide and connect the arclen to input1X in a multiply divide node. I put in ive 141.789 into input2x and connect outputX from the multiplydivide node to each joint in the chain. here is the problem as seen in picture 2 and three the end joint where the joint chain ends goes crazy and extends beyond its position if i pull the curve too much is there a way to solve this? if anyones interested in helping me, or know a better/smarter/more efficient way to do it please let me know! And want to see the file itself ill gladly email it to you http://s21.postimage.org/ng29sk0fr/Capture1.png http://s21.postimage.org/6gtbdap87/Capture2.png http://s21.postimage.org/sh9ntx7w7/Capture3.png |

I think it's the downside of using spline IK. The spline ik tends to overstretch itself. I believe it has something to do with the calculation of the arclenght and the round off of the numbers. I could be wrong though
![]() It's probably not the answer you were looking for but I hope it helps you anyway. good luck with the project |
