Broken IK Controls

Hi everyone,
I’m very new to procedural foot placement — this is my first time working with it — and I’ve run into a problem I don’t know how to fix.

1 1. What am I trying to achieve?

I’m trying to get Inverse Kinematics (IK) controls to work properly for my character’s feet, similar to what’s shown in this video:

Everything was working as expected originally. That video shows my intended result — smooth foot placement using IK controls.

2. What’s the problem now?

After updating Roblox Studio, the IK behavior suddenly changed. Here’s what it looks like now:

As you can see:

  • The legs flip or bend in the wrong direction after moving from a straight pose.
  • During playtests, each “step” causes the leg to rotate incorrectly and jitter, unlike the first video.

3. What have I tried so far?

  • I tried adjusting the pole vectors (pole attachments for knee direction).
  • When I add the poles, the legs flip or bend backward unexpectedly.
  • If I remove the poles, the flipping issue is fixed, but the legs bend in the wrong direction — backward instead of forward.

I’ve looked through the Creator Hub and forums, but I haven’t found a clear fix for this behavior.

:question: Any Help?

Has anyone else experienced this after a recent Studio update? Is there a proper way to handle pole vector positioning now, or has something changed with IK behavior in newer versions?

Thanks in advance for any guidance!
