I have been helping a co-worker learn some rigging techniques, and since I'm essentially making tutorials, I figured I might as well post them for others to benefit from as well! Today's topic is how to make an IK limb stretchy.
The basic idea is that we will measure the original length of the IK from start joint to handle, and any time that distance increases beyond its original value, the bones of the IK limb will scale to make up the extra distance rather than rotating beyond what makes sense (the cause of popping).
Let's dive right in!
