I just sent a bug report. I can’t believe nobody ran into this problem. And yes, I have a Unity License.
How to reproduce:
Start a new project using Unity 5.6.0 or higher
Import Google Cardboard VR v1.5 or 1.6
Change splash screen settings
Build for android - Splash screen works correctly
Add “Cardboard” to the “VR SDK’s” list
Build project - App will display the default gray “Made in Unity” splash screen
This is a huge show stopper for me right now, I have a project due in two days and the client specifically wanted their logo on startup. That feature is literally the only reason I bought a license, and it doesn’t work.
