  1. What do you want to achieve? I would like to be able to animate a katana with it’s sheath

  2. What is the issue? Whenever my animator tries animating the katana and sheath its only moves one or the other.

  3. What solutions have you thought of so far? We tried grouping the sword and sheath as well as welding.

We are using this method to animate btw How to animate Tool Parts (Guns, Knifes etc.) and this is the issue that keeps happening https://gyazo.com/c907fcdc45ae4f569a5ca5062ec0dd50
