the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > modify the Unity game resources you need to use special tools, here are several possible tools:
Unity Asset Editor: This is a Unity resource editor, which can open Unity resource files, such as scenes, materials, textures, audio, and so on, and can modify, add, delete and other operations.
UABE(Unity Assets Bundle Extractor) : This is an open source tool that can open Unity's resource files, export them as standalone files, then use other tools to modify them, and finally import them into Unity.
AssetStudio: This is an open source tool for viewing Unity resource files and exporting to other formats such as.obj,.fbx, etc. However, unlike UABE, it does not support importing modified resource files into Unity.
