Child not following parents transforms.

Unity Engine

I have a sword attached to a model. I have added an empty game object to the sword so I could add a collider to it. The empty game object is not following the sword, and I can’t figure out why. There are no scripts effecting the empty game object at all. There is a rigid body and a capsule collier at the top of the characters hierarchy.

Figure 1 - The hierarchy of the character. Rigidbody is on the Knight object, SwordCollider is the empty game object with the collider on it.

Figure 2 - Character in the scene view. Collider is right on top of sword here.

Figure 3 - Character during game play, notice the capsule collider follows the rotation of the entire knight, but not the sword like I want.

Can someone please explain to me why not? I have been struggling with the relationship between the parent/child hierarchy and how the children are effected. It doesn’t seem to work intuitively. Many thanks.

Thats pretty weird, are you transforming thr sword using world or local space?

How can I tell for sure? I believe it is local space. When I move the entire character around the values for rotation and position in the swords transform do not change.

I was able to solve this problem by parenting the sword collider object to the players hand bone and not the sword object.

It was probably due to non uniform scale somewhere in the parent(s).
