무기가 캐릭터에 겹치지 않게 보이기

1. 컨트롤 릭 변수 추가

2. 컨트롤 릭에서 기본 자세 설정

3. 클라이언트 매시 복사를 위한 코드

4. 애니메이션 블루프린트 설정

1. 콘텐츠 브라우저에서 생성하고 싶은 파일 내에서 오른쪽 마우스 클릭

2. 애니메이션 블루프린트 생성

3. 애니메이션 블루프린트에서 변수 추가

4. 아래와 같이 설정

애니메이션 블루프린트의 Event Graph에서
애니메이션 블루프린트 AnimGraph에서

5. 블루프린트 설정

1. 블루프린트에서 Client Mesh에 지금 만들었던 애니메이션 블루프린트를 적용
