I have a dataset loaded in unity to work with vive. It works as expected if I play the scene in the Unity user interface. I want to send this package to someone who doesn't have Unity installed and just wants an executable. I tried to build it into an exe but when I run it I see only a gray screen. Both on the monitor and the HMD. Could someone know what I am doing wrong, I am really new to this. I am using the 2017.3.1 version. Thanks a lot!
