This isn’t necessarily a problem. The integration uses on FMOD studio system while in the editor, and a second while in the game (or PIE). The system used in the editor is for auditioning and general information querying, and we don’t load plugins into that system for stability. If its printing that warning in the editor at startup you can ignore it. The error you want to keep on eye out for is a red error when running PIE that says “DSP plugin returned an error, bank will not load properly.”.
Other than that, there are two things to be aware of
- Make sure the Oculus .dll you use is the same version in FMODStudio\Binaries<Win64 or Mac> as the version you used in FMOD Studio.
- In FMOD Studio Oculus project settings, click “Oculus Enabled”. That should load the plugin for you when you run PIE or launched game.
If you are still having problems, try posting a new Q/A on FMOD and we can dig into why its not working.
