Hi Dennis,
If you open your FMOD Studio project then go into Edit > Preferences, and click on the Build tab, you can see a “Built banks output directory”. Create a new folder in your Unity project folder and set the bank output directory to this folder.
In Unity, you will need to change your FMOD Settings to Single or Multiple Platform Build and change the Build Path to this new folder.
You can now add the built banks folder to Unity Collab and everyone involved in the project can use the FMOD banks.
Thanks,
Richard
