Can you show a screenshot of the inside of the the character blueprint? (to see the hierarchy). It would help to diagnose how to detach the sword
The sword could be
- a separate actor
- an actor component
- a static mesh component
- a component derived from scene component
or worse case scenario baked into the character’s mesh
You could attach a box collider and attach it to the mesh at a socket attached to the hand and use that for hit detection
