When I open Unreal Editor, AssetLookUp.uasset is changed.  
I find some Log in OutputLog, I hope it’s useful.

Thanks for reporting this, it is something we are aware of and are looking into.

> When the banks on a given machine change (eg. from source control or locally built) the FMOD plugin will attempt to generate any new assets and modify any that require modification. This will occur if the editor is open or the next time it is opened. If events, buses, etc have been added or removed from the FMOD Studio project, the AssetLookup.uasset will be modified and checked out of source control (as exclusive checkout, which appears to be the default for .uasset files). Hypothetical: So…

I meet some trouble with this.  
When I open Editor, it while change AssetLookup.uasset and BankLookup.uasset and everything is perfect.  
But when i package project, AssetLookup.uasset and BankLookup.uasset are not changed, it works wrong. Some Event not found.  
So what happened? Why files not changed by Editor cannot find some Event Path?

The lookup files should be rebuilt when the banks are modified.

Are you packaging from the editor or command line?

Can you share your output logs at all?

I’m sorry I reply so late. Happy Lunar Year.  
We have solved this problem.  
When FMOD starts, it will automatically decompress the resources and will be modified to the AssetLookup file.
