Fuck. This is what happens when I don't mess with unity for months, having a simple issue and I don't remember how to fix it.

I added a dynamic bone to a chain and added it to my model, in unity when I move the model around (in play mode to test the dynamics) it shows the "bone" of the chain moving, but the chain itself is just standing still, as if the bone is not affecting the chain at all yet the bone is wiggling around. I know the bone is weighted to the chain because in blender it properly moves the chain. How do i fix this? blanking completely on why this is happening
