Is it possible to use pole targets with IK chains of more than 2 bones (like tentacles)? I am currently experimenting with such a setup, and adding Pole Target causes entire chain (except one joint at the base) to lock up in rigid state
hello, maybe share this part of your armature: https://pasteall.org/blend/
Okay, if I’ll encounter more problems, I’ll share the file. For now, I seemingly found a workaround. If I bend the chain slightly in Edit mode, so it isnt completely straight, it helps to “unstuck” it https://gyazo.com/adf3f32e52ee947726780eda5c0ff59d https://gyazo.com/fda61a64e130e66a60b3afc115d98899 IDK why I even need to use this hack, because Pole Target is already supposed to do similar thing (point to what plane IK is calculated on), but at least it works as expected now
yes you always need to bend the limb a bit so that Blender knows how to bend
Another problem: when I “brute force” the IK resolution as described above, the entire chain flips around when pole target is moved, instead of bending in another direction. Not fitting behavior for hair or tentacles. Perhaps its beyond the IK capabilities, but is there any way to change it? https://gyazo.com/8e2eb26d76e8734a0928f3625d4834ee how it is currently and https://gyazo.com/e789806abf8bc2d764632eba1352983d how I would like it to behave
I don’t know if there’s a way to solve that, maybe you should create 2 IKs (one on the middle of the tentacle) so that you control your whole tentacle with 2 controllers (or use another rigging method like Spline IK?)?
Yes, Spline IK with Hook - controlled spline vertices it is. Thanks!
