Find the Penguin Unity Sample Not working

December 12, 2016 - 8:29am #1

I am running the latest Vuforia downloaded today and the Latest version of Unity on Mac.

I have also got a Image marker working in unity with a random model I imported form blender. So I know Vuforia + Unity + Xcode works fine.

This is likely a problem with how I implemented the sample as I am relatively new to Unity.

The problem I am having is when I run on iOS I get the errors:

NullReferenceException: A null value was found where an object instance was required.

  at PoseController.RotateToLookAtCamera () [0x00000] in <filename unknown>:0

  at PoseController.LateUpdate () [0x00000] in <filename unknown>:0

(Filename: currently not available on il2cpp Line: -1)


Here are the steps that I followed to build the sample.

1. I downloaded the "FindThePenguin-6-1-17.unitypackage" from the samples download "vuforia-samples-practices-unity-6-1-17"

2. I then created a new 3D project with analytics in Unity called FindPenguin

3. I went to the menu item:  Assets -> Import Package -> Custom Package

4. From the finder window I selected the "FindThePenguin-6-1-17.unitypackage"

5. Using the project navigator I went to: Assets-> Scenes

6. I draged all three scenes from that folder to the Hierarchy window insuring the order was 0 to 2

7. I went to menu : File -> Build Settings

8. Pushed the Add open scenes button also made sure the order was correct 0 to 2

9. Hit Build 

10. added my signing credentials to the new Xcode project 

11. Compiled onto device running iOS 10.


What happens:

1. the Splash scene displays as expected 

2. the Loading screen appears as expected and asks to access the camera that I grant

3. the AR scene loads with the text as expected but no camera view just a black screen and the above mentioned run time error


If any one has any ideas as to what I am doing wrong it would be greatly appreciated.

The above steps do work you just need to remember to add the licence key to the camera >.<

The error in no way explains this but with fresh eyes I realised I forgot to add the licence.
