Hello, the FMOD STUDIO version we are using is 2.01.10.

When I modify an asset or event, or add an asset or event, click File-\>Build. In git, all bank files are changed.  
This will prevent us from automating the packaging of AssetBundles.  
Are we using the wrong method? Or is there other work that needs to be done?

Thanks

Today, we found that when a teammate using Windows exports, only the specified bank changes. Therefore, we think that MAC and windows export different banks for the same Fmod project, so we will use the same system to solve it later.
