I rebuilt my project in Unity 4. It shows fine in the editor, in the web player, in the iOS Simulator. However, when I run it on my actual iPad it shows the Unity logo and then goes to a black screen. The strange thing is I can still interact with it in the background as when I click on places on the screen I can hear the associated sound effects. Any thoughts?
This is also happening on Android devices, so not something specific to iOS, but something specific to deploying out to mobile/tablets.
I may be seeing something like this, but it's just that any textures are missing. So I can see where things should be, but no image/textures. UPDATED: For me it was a lighting issue - my light was washing out my images. I lowered the light and it worked. Not sure why it would be so different from Unity preview to iOS???
Have you tried upgrading to Unity 4.0.1? If problem persists please submit your project as bugreport. Thanks!
