Create a root spline.
I create my feather (with the feather tool over this spline).
Convert the feather into hair ( my feather comes dynamic , the same shape but now is hair ).
After that point , animate my root spline with spline dynamics but I can't link the Hair feather to this animated spline
(the feather follow the spline before I convert it to hair but after this, I can't connect it ) (obviously is not a solution leave the feather just in feather mode)
Maybe I'm skipping some step or maybe there are some tricky way to connect this two things. I hope someone can help me solve this problem
