Hi , I’m just trying to package my game for GoogleVR for distribution for any API not for Daydream, sorry. I haven’t used UE 4.14 but I have read on forms about previous versions that if Unreal Engine is at Preview stage its not meant to Package games or ship them because its still busy with fixing bugs etc.
But I see you want to build for development.
Have you tried maybe disable all other plugins you don’t use and run engine in admin mode. Or try to set the deployment mode to Daydream & Cardboard.
I see on your form you said something of a game you already created for GoogleVR did you uploaded it on the Play Store?
