Hey folks, this may have been obvious to some people, but if anyone is interested in knowing how to get your armature IK to have an effect on a curve, I’ve put together a small HOWTO. The gist of the thing entails using Hooks to simulate the functionality of weight painting. Until we can actually get armatures to work on curves and NURBS, this is a pretty decent solution. This way, you can do rigged 2D animations like in Moho… and you can probably even rig a fully NURBS model for IK.
Check it out and let me know what you think. Hopefully someone else besides me finds this helpful.
