Part of this problem could be resolved if the command line tool had an option to specify the folder .banks when into… Is there one?
At the time of writing (March of 2019) there is no option in the FMOD Studio command line tool to specify a different build directory.
That being said, it does sound like a useful feature to have. I’ll add it to our feature/improvement tracker, so that it will be added in an upcoming release of FMOD Studio.
Or is there a way to have one project built .bank files to different locations based on the user (env var?).
There is currently no supported way of doing this… But you could potentially create a batch process that performs the build then moves the built bank files into a location specified in that batch process.
