UE 4.20 and FMOD

I believe you would need to install 1.10.09 version.

However, when I tried to compile it from the project’s directory, I get 1>..\Plugins\FMODStudio\Source\FMODStudio\Private\FMODStudioModule.cpp(25): fatal error C1083: Cannot open include file: 'IMediaClock.h': No such file or directory.
Probably, putting it into engine’s plugins directory will help.

Update: or just put Runtime/Media/Public in all the IMedia* includes.
