[수정] Unity 6.2 에서 Dot(.)이 숨겨지긴 하지만 빌드에서 제외되지 않는 버그가 확인돼서 Dot(.)과 Tilde(~) 둘다 붙이도록 수정함(Tilde는 빌드 제외 되는 것 확인함) [2025-08-28]
※ 아래 링크에서 설명을 보면 StreamingAssets 폴더 하위에서 dot(.) 정책이 변경 된 것 같다.
[Hidden assets] https://docs.unity3d.com/Manual/SpecialFolders.html
- Files and folders which start with ., except for those under StreamingAssets where this pattern is not ignored.
[수정] Rename 방식으로 변경 [2024-07-04]

[빌드 시, Builtin AssetBundles에서 해당 Platform 에셋번들만 빌드 되도록 하기 위한 PreProcessor 추가]
기본적으로 에셋번들은 플랫폼 별로 모두 가지고 있는데 해당 플랫폼에 맞는 에셋번들만 빌드 되도록 하기 위해서
빌드 전(Preprocessor) 해당 안되는 AssetBundle을 Hidden 폴더(예: .Android / .iOS)로 Rename 했다가, 빌드 후(Postprocessor) 되돌려 놓음.
빌드 전(Preprocessor) 해당 안되는 AssetBundle을 Hidden 폴더(예: .Android~ / .iOS~)로 Rename 했다가, 빌드 후(Postprocessor) 되돌려 놓음.
