I’m trying to figure out how you’d go on about making an armature constricted to 2 dimensions (x and y) with IK. I’ve tried adding rotation limitation constraints to the bones, only allowing them to rotate round Z, but the bones start behaving funky if I do (together with IK). I found this video on vimeo:
So I know it’s possible. In the video the bones somehow seem to be constricted to 2 dimensions automatically for some reason. If I try doing what he does in the video, the bones will start going “upwards” if the IK handler gets too close, to solve the constraint. (See the attached file.)
Preferably, I’d like to use Auto IK if it’s possible to do so with a 2 dimensional armature.
Any help please?
