위에 쓴 명령어는 실수로 오타를 적었네요 계속 정상적으로 *.pac 사용 했습니다.  

제가 작업하는 과정을 언팩부터 설명해드리겠습니다.

수정하고싶은 Pac 파일 : pdw_10_ub_0074.pac

PS C:\Users\sshine\Desktop\PACtool> .\pac_to_dae.bat

위의 출력 결과로 3개의 매쉬를 얻었고 제가 필요한 옷은 mesh02에 있기때문에 mesh02_lod0.dae를 사용했습니다.

이후 수정하여 test.dae로 저장을 한뒤

PS C:\Users\sshine\Desktop\PACtool> .\dae_to_pac.bat

C:\Users\sshine\Desktop\PACtool>PACtool.exe -r test.dae pdw_10_ub_0074.pac bones/ppw_01.pab

이렇게 다시 pac을 만들었습니다.

확인을 위해 다시 pac을 dae로 전환해 보면

위 처럼 mesh00_lod0.dae파일이 제가 수정한 모델링이 들어가고 나머지 파일들은 그대로 있기 때문에 인게임에 적용하면
mesh02에 있는 원래 옷이 노출되고있습니다. 제 작업과정이 어떤 실수가 있는지 알려주시면 정말 감사하겠습니다.
