Me and my programmer keep having issues with my music system (were using fmod 2.03.09 and unreal 5.6.1), I don’t even know how to describe the issues but pretty much we think its a fmod issue, and the only error output on the unreal side of things is “failed to set parameter” (I’m using 1 parameter to transition between tracks i.e hub to levelintro to mainloop and back to hub). I can send screenshots of our bps but I’m also wondering how i can get a debug log or something through fmod? Let me know if i can expand on anything, but any help would be greatly appreciated!!
Thanks for your reply!
Unfortunately it wont let me upload the log as a file to the forum, I could copy and paste but its quite large so I dont know how effective that would be,
Here is the Fmod parameter
Here are the bps in Unreal, some parts of this are deprecated, let me know if there seems to be any information missing (i only just realised i cant put more then one image per forum post as a new user, if you’re ok with it, I made a google drive folder with the rest of the screenshots, as well as the output log)
Thanks so much for your willingness to help!!!
The google drive is great, thank you!
From the logs I can see
LogFMOD: Error: System::setParameterByName(MxController, 0) returned error 74 ("The requested event, parameter, bus or vca could not be found.") for instance type: 11 (0x2097023).
LogFMOD: Warning: Failed to set parameter MxController
LogBlueprintUserMessages: [BP_XG_AudioParameterManager] mxcontroller: 0
Looks like the parameter isn’t being loaded correctly, which is odd as global parameters are loaded with the FMOD system rather than an event.
Could we please try regenerating the FMOD uaassets? Rebuilding all the banks with
It may be the the banks are stale and are missing the parameter?
This worked! Kind of, now the issue is that the music doesn’t play during levels, so it is playing which is awesome but only in the hub. This might be something I have to ask the programmer about though as he’s set it up for the most part, do you have any insight? Thank you so much for your help!!!
Good to hear that is working, are there any more errors in the logs indicating while the music might not be playing?
Honestly, not that I can find, Ive uploaded a new copy of the log into my google drive if you’re willing to take another look, I cant seem to figure it out, the trigger should be on our audioparameter bp so I don’t know why it isn’t functional
Thanks for the updated logs, I cannot actually see any events being triggered at all. Could you add some additional print nodes after triggering the events to make sure that are being called?
ok so ive had a chat with my prgrammer, we still have no clue what the issue is, its not to do with the music being triggered, and the parameter is sending all the information accordingly, is there any other obvious gotchas that i could be missing?
Could you please record a profiler session: FMOD Studio | Profiling and package it with the following settings:
It can be uploaded to your profile. This can show us if the events are triggering as expected and if the parameters are the expected values.
