Workaround: Compiler errors with Unity 2018.4

May 7, 2019 - 2:37am #1

With Unity 2018.4 LTS, you might see compiler errors like below when using Vuforia:

Assets\Vuforia\Scripts\Internal\RuntimeOpenSourceInitializer.cs(61,63): error CS0234: The type or namespace name 'ScriptableRenderContext' does not exist in the namespace 'UnityEngine.Rendering' (are you missing an assembly reference?)

This can be easily resolved by opening that script, and change all occurrences of

#if UNITY_2018_3


#if UNITY_2018

Known issue: Vuforia 7.5.26 does work with .NET scripting backend on UWP in Unity

October 31, 2018 - 8:59am #1


A regression was introduced with Vuforia SDK 7.5.26 in Unity where using the .NET scripting backend will throw an exception when running a Universal Windows Platform build. This also includes HoloLens apps.

Please use the IL2CPP scripting backend instead, where this issue is not seen. We plan to fix this issue in an upcoming release.

Known issue with Unity 2017.4 LTS iOS builds

September 13, 2018 - 3:54pm #1

Hello all,

A crash is seen on iOS when using Vuforia 7.0 in the Unity 2017.4 LTS version (2017.4.5 and later) when using Metal graphics API and Autorotation. There is a work around available. Disabling the "Multithreaded Rendering" option in Player Settings will prevent this crash from occurring.

This issue is not present in more recent versions of Unity and Vuforia. Unity 2018.1+ and Vuforia 7.1+ do not encounter this issue and can be used without the workaround.

Known issue after importing Vuforia samples on 2018.1 & 2018.2

July 18, 2018 - 3:59pm #1


Recently, Vuforia released 7.2 SDK with updated samples to the Unity Asset Store. These samples are not compatible with the 7.1 SDK, which is already packaged with most (if not all) of the current versions of the 2018.1 and 2018.2 Unity Editor.

The most common Vuforia error message observed is the following: "The type or namespace name `FusionProviderType' could not be found. Are you missing an assembly reference?"

Known issue when submitting a build to Testflight with Vuforia 7.2.20

July 12, 2018 - 11:23am #1

Hello all,

There is an issue with Vuforia 7.2.20 that will prevent you from uploading your iOS app to TestFlight. The cause of the issue is that the “Bundle Version” field of the Info.plist in the Vuforia.framework is blank. This issue can be worked around by opening the Info.plist file and adding a number value, such as “1,” to this field.
