I have a character I need to scale for different scenes. I can't get the edited particle hair length/direction to scale with the mesh. It is at least emitting from the same location. I've tried disconnecting the hair and applying scale on the mesh then re-attaching the hair but it doesn't make a difference.
Using the disconnect method seemed to work for edited hair on a cube with 'quick fur' attached but doesn't for my finished/rigged character.
