UnrealEngine 4 Git, .gitignore

언리얼 엔진4에서 Git을 사용 할 때 불필요한 파일들은 무엇일까요?

처음 UnrealEngine의 프로젝트를 StarterContent를 포함해서 생성했을 때 보여지는 디렉토리의 크기입니다.

여기서 언리얼 엔진이 다시 생성해주기때문에 필요없는 폴더들이있는데 아래와 같습니다.

/Binaries
/Build
/Intermediate
/DerivedDataCache
/Saved
[프로젝트 명].VC.db

이 폴더들을 지운 후 용량을 체크해봅니다.

무려 800MB가량이 줄었습니다. 놀랍게도 남은 632MB 는 거의 StartContent Resource가 대부분입니다. 

이제 이 지운 폴더들이 없다면 .sln 솔루션 파일을 통해서 프로젝트를 열려하면 제대로 하위 프로젝트를 연결하지 못할것입니다.

그럴때는 .uproject 에 우클릭을해서 Generate visual studio projects files 버튼을 누릅니다.

그러면 다시 열었을 때 제대로 연결된 모습을 보실 수 있을겁니다.

최종 결론 !

.gitignore 파일에 다음과같이 추가합니다.

# UnrealEngine Generated Files
*/Build
*/Binaries
*/DerivedDataCache
*/Intermediate
*/Saved
# StarterContent를 형상 관리 하지않을경우
# [프로젝트 명]/Content/StarterContent/

# VS Generated Files
*.suo
*.db

https://www.gitignore.io/ 에 가셔서 Visual studio, UnrealEngine을 선택하면 다음과 같은 gitignore 파일이 출력됩니다.

이 파일을 이용해서 git에 적용하셔도 됩니다.

아래의 폴더/파일만 남겨두면 .uproject 파일을 실행시켜 프로젝트를 다시 세팅할수있습니다.
