After I did build (press launch) then I lost sounds from FMOD. Ordinary sounds work perfectly. What could be the problem? ---

The most likely situation is that the banks aren’t being packaged up. You will need to add FMOD as a directory in the packaging settings. See this page for more info: [http://52.88.2.202/documentation/#content/generated/engine\_ue4/deployment.html](http://52.88.2.202/documentation/#content/generated/engine_ue4/deployment.html) Another common problem is that you are launching on a different device, which will look for different banks (e.g. iOS and Android look for banks in a FMOD/Mobile directory, not under FMOD/Desktop). ---
