I have two armatures.
I used follow path on one of them as bone constrains attached to a curve.
When I change offset of follow path this armature moves as it is supposed to be moving. Following path.
Then I select other armature and then the armature I added constrain and used copy to selected in follow path constrains drop down menu. Now the other armature have the same path to follow and if you select it and change offset it moves with the shape of this path.
But what I want to achieve is move both armatures with curve shape when I change only one of their offset.
Well, after selecting all armatures hold pressing option button (for Mac) and change offset with mouse.
