Hmm, I’m not sure right off. Something is definitely wrong as it’s not supposed to be working like that. The TwoBoneIk scene in the example project works on your machine, right? Just wanting to make sure in case it’s something OS specific (I doubt it, but never hurts to cover all bases)
If possible, can you send me the project and/or a minimum replication project? If you want, you can send it to my email: clanbn@hotmail.com
Edit: changed the tag to “bug report”, as there is a bug of some sort happening.
I sent an email with a link to the project with TwoBoneIK working. :)
For anyone looking at this post in the future: The issue was just that the second bone, the lower leg, didn't have its length properly set. I just added another bone as the child of the lower leg and set the bone ID to the foot, then it worked as expected.
