These props are supposed to work regardless of the animation, you just have to trigger the name of the prop in your food script for example.
But it’s possible that the rotation and the position is not optimal according to the animations, it is therefore necessary to modify them.
A list of coordinations is provided for the basic eat and drink animation :
