What is causing jumpy physics when I use constraints?

I’m running into an issue where I can’t get smooth physics interaction between a physically simulated sword and a static shield with collision. I’m using a physics constraint to allow some give between the sword anchor position to where physics pushes it to, but it becomes extremely jumpy as it solves it constraint during motion of the anchor.

Does anyone have any ideas of how I could make this effect more consistent?


Did you find the issue?
