This is an issue with plugins and binary only projects. If you download the UE4 binary and create a blueprint-only project, then code plugins won’t be linked into your final executable. It just doesn’t work. We recommend the same as the other code plugins, which is to create a code project even if you don’t want to add any code classes to your project.
If you do create a code project (even an empty one), then it will link correctly. You will then have to do two steps to get deployment working:
- Ensure that the FMOD directory is included in the packaging settings.
- Manually copy over the FMODStudio third party DLLs to the StagedBuilds directory once deployment has finished.
See the Deployment section in the chm for more details of the above steps.
We have raised support issues with Epic and I’m hopeful these will be resolved in time (although unfortunately they aren’t fixed in 4.5 by the look of it).
