Known issue: Package Manager upgrade to Engine 8.3.9 is incorrect

August 2, 2019 - 1:23pm #1


Unity has informed us that due to a Package Manager issue, the 8.3.8 version of Vuforia Engine was incorrectly listed in Package Manager as 8.3.9.

There is currently no 8.3.9 version of the Vuforia Engine SDK, so this is a false notification.

Apologies for any inconvenience.

Suggested workaround when accessing Unity materials interferes with background texture updates

June 5, 2019 - 2:57pm #1

Vuforia Engine requires a specific setup for the material and its textures in order to ensure that the video background is rendered correctly each frame. Our workaround solution is to not directly use the VB material (which create a new instance), but create a new material and reference textures from a reference to the first one (i.e. sharedMaterial). Our example creates a shallow copy and does all the necessary setup required for rendering the camera feed.

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

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?"
