    I use the Multi-Parent constraint to attach weapons to my character's hand. I use this system because sometimes the weapon may be sheathed, so I only want it to be attached to a hand sometimes. The weapon is attached to a weapon bone, and the constraint works well for normal animations. However, I get an issue when it is paired with a Multi-Aim constraint. The multi-aim constraint is used to aim the character's spine to get it to look in certain directions. However, any transformation of the bones as a result of the multi-aim constraint target moving does not affect the Multi-Parent constraint, so the weapon does not move, it remains in the same place as if the hand has not moved. However, the target of the multi-parent constraint is a child of the hand bone and although the multi-parent target moves with the hand bone with any multi-aim constraint movements, the actual weapon does not follow the target.

    Does anyone have any idea why this is?
