Build succeeds but camera renders black screen on iOS

I have two scenes in my build, a title screen and the game proper. I can build it to my iPhone fine, but when I open the app a couple of strange things happen:

1. The Unity logo is skipped, even after a full restart of the app
2. My Title scene works fine, but once I initiate the scene change to start the game..
3. The screen goes black, with the exception of a simple GUI string displaying the fps.

This leads me to believe that the scene is running, but the iDevice doesn't agree some rendering process I am doing (which afaik is nothing fancy). My quality settings are currently set to Simple, which I have not had a problem with before. Any ideas how to trouble shoot this?

 

I got a similar problem.
Two scenes, one menu, one game. Game starts and I hear the background music, but just see a black screen. When I tap the screen, I do get the UI layer to display properly (like it should in my case, after tapping the screen).
Game scene itself works fine.

Should mention I have two cameras in the scene, one that's rendering the main action and another rendering an element in front of everything.

Main camera:
- Clear flags: Don't clear
- Culling mask: Everything except 'CameraFront'

Front camera:
- Layer: CameraFront
- Clear flags: Solid color
- Culling: Just 'CameraFront'

Works fine on e.g. Standalone Mac build.
Problem seemed to appear with 5.3.2f1 but can't confirm 100%.

 

The guys over here seem to be on to it: http://forum.unity3d.com/threads/3d-rendering-issues-on-ios-with-unity-5-3-1.378446/
So 5.3 breaks metal rendering on iOS it seems.

 

Me too, this error occurs 5.3.2p2,5.3.2p3,5.3.2p4!

 

Sadly, I get the error after downgrading to 5.2 too... maybe it's related to the new XCode version.
Looks like I got to sit this one out.

 

Glad you found what was causing your issue. In my case, it turns out to be altogether different. In the interest of helping anyone who encountered the same issue that I did, turns out it that for me it wasn't a rendering issue, but rather an iPhone issue with the interpolation of the rotation in the animation (mouthful) of my camera. By default, interopolation is set to Euler Angles, which was causing my iPhone 6 to return the camera's rotation as NaN. Changing the interpolation to Quaternion solves the issue. You can change the interpolation of an animation by navigating to the Animation window, right clicking on Rotation, and selecting Interpolation > Quaternion.
