I made a person in blender with a soft body ponytail, and it worked fine. For some reason, though, when I added an armature to the model, the soft body on the ponytail stopped responding to side-to-side rotations, but reacts fine to up-and-down rotations. Does anyone know why this would happen?

The person also has a dress on, and the dress is just ignoring the deformations made to the body by animations, and acting like the body is just sitting in its original pose with no animation. Everything worked fine before I made an armature for it.

Nevermind, I fixed it. It was a problem with the ordering of the modifiers. I probably look kind of silly now, having a conversation with myself on a forum

Maybe so. But this might also help someone else. Thanks for following up.
