Sync Head Slot Item with Player Animation

[lupusmalus]

🐞 Feature Description

I would like the item in a players head slot to be synced with player animations.

Similar to the in-hand items, any item can be used on the head. Playing a player animation makes that item disappear. I'd expect it to work similarly to in-hand items: Add a special bone to the player model, sync the item in the players head to the model animation
