I don't know about your particular setup, but usually IK popping is fixed by setting "Bone Properties -> Inverse Kinematics -> IK Stretch" to a small value. But if it's for a spline IK or Bbone, I'm not sure whether it'll help.

Oh right, and if you don't know about bendy bones, you should have a look at some tutorials. Not as flexible as spline IK, but it's a simpler setup.

Yeah I believe GN will open a lot of options for all sorts of animation aspects, but I'm looking to use it for rigging. Speaking of, your's seems pretty nuts! And despite the amount of strokes and geometry, the deformations look great! Fantastic work!

Been a while since I worked on this GN setup, but I do remember hitting a blocker of some sort, and not being able to use this in the animation I was working on. Think it had to do with not being able join the modified layers back to the original animation without messing up the layer order.

You're doing your part by spreading awareness. You've also got the skills to convey your ideals and emotions in art. Make the most of it, I'm sure your comrades will appreciate the work you put in.

Could partially be due to the EU nsfw content block.

Here's my current node setup, for anyone who's interested. It just uses the target objects location, instead of geometry, so pretty simple stuff. Grease Pencil doesn't yet support the Attribute Statistic node, hence the conversion to curves.
