My programmer is getting this error when building our game from Unity. I do not get it on my computer. Any idea about what could be wrong?

> [FMOD] RuntimeBankModel::openFile : Failed to open file ‘F:/Unity/Projects/PandaBall/Builds/build/PandaBall\_Data/StreamingAssets/MainMenu.bank’

Thank you!

Do you have the Unity project’s FMOD settings set to use the project instead of prebuilt banks (Single/Multi Platform Build)? If your programmer opens up the StreamingAssets folder can they see the “MainMenu.bank” file in there?

After making another build the problem went away, so let’s hope it was just that one time 🙂
