Cloning
Users have the option to clone avatars directly from other users. This feature allows users to adopt the same avatar they see another user wearing by selecting the user and utilizing the "Clone Avatar" button within the Quick Menu. If this option is unavailable, it indicates that the other user has disabled the cloning feature, or is using an avatar marked as private that was specifically uploaded to their account.
