Unable to load banks for another platform at runtime

[rafa_randy]

Hi!

I’ve come across with a deadend while trying to manage different speaker setups at runtime. As you explain in the documentation, I try to approach this by using different platforms for each speaker setup:

• Desktop (for TV)
• Desktop Headphones
• Desktop Surround (5.1)

The problem is that, once I “Build for All Platforms” to the UE path (Content\FMOD), this is the folder structure I get:

There is no trace of other platforms rather than Desktop, as you can see, and it seems to have unique folders for Events, Banks, etc. So if I want to Load a bank metadata to switch the speaker setup, there is only one Master.bank in all the project.

If I go to the Content/FMOD folder using Windows Explorer, the different platforms folder are actually there, but they don’t show in Unreal.
Besides, if I change the name of the Desktop platform within FMOD Studio and Build, it doesn’t load/update anything on Unreal.

Is this a known issue or am I the only one struggling with this? How should I proceed to manage different platforms?

Thanks!

Hi,

Thank you for all the information. What version of the FMOD integration are you using?

Could I please get a screenshot of your Project Platform in your Build Preferences

Could I please get a link to the documentation you are referencing?

When saying platforms here, are you referencing Windows, macOS, Android, or the platforms or possible speaker setups?

Could I get a screenshot of this too, please?

Hopefully, this is not a bug and we can figure it out.

Hi Connor,

First of all, thanks for your reply.

Thank you for all the information. What version of the FMOD integration are you using?

I am using 2.02.

This is the documentation I mentioned:
https://fmod.com/docs/2.02/studio/advanced-topics.html#setting-up-different-audio-configurations-for-your-game

And according to it, the Build settings should look like this:

, where you add a platform to handle each speaker setup for each “real” platform. I guess the problem is that the Output Sub-Directory is hardcoded in the Unreal Integration, so you can’t actually rename it “PC Headphones” (as in the screenshot) because the integration is expecting “Desktop” only.

I mean possible speaker setups per platform: Headphones, TV and Surround 5.1 on PC, XBOX Series and PS5.

I removed the extra platforms from the project because it didn’t work, but it looked like this:

being Desktop Surround the one with the Output sub-directory as “Desktop”.

Correct me if I am wrong but I assume it’s not possible to use this “platform per speaker setup” approach with the Unreal integration if the Output sub-directories are hardcoded, right?

Thanks!

Not necessarily, an option may be to manually load the desired banks from your custom locations using: FMOD Engine | Studio API Reference: Studio::System::loadBankFile.

This would require disabling the Load all banks setting:

and creating a class to load the desired banks for you. Please let me know if you need assistance implementing this.

I will suggest creating some tools in our integration to improve this workflow. Thank you for bringing this to our attention.
