And also didn’t forget to check you blueprint with chosen model. Keep in mind, that need to define root component as any collision component (box, capsule. etc.) as root element and mesh as it child. It’s really important, because otherwise model doesn’t rendered in a hand of monster.
Ok and… how can I do this? My attached object (ball) is already in the Character but it’s not in the hand (where the socket is) and its behaviour is static (not moving with the running animation).
