Im sort of testing to rig a human spine (neck part) by using spline IK in maya.
so i ve built a curve with CV points amount exactly the same as the spine models. then i also attached joints along the CV points which are centered to the spine models. and i had another separated joints only to control the curve so it can bend along the axis. i can control the amount of CV points that being influenced by controlling the amount of weights of each CV.
i used a circle and a locator here just to make the movement more visible and clear. but the problem is when the joints bend to a certain degree, you can notice that the IK spline kinda jumped so it affected the spine to be off from the position. am i missing something or there is another way to fix this? i ve heard that maya IK spline sometimes can be buggy and some use another trick to build similar effect and less buggy.
thanks for reading!
