Hi,

With Vuforia Engine 8.6 SDK, we've made some changes to our upgrade/install Path.

Please check out following article for more info: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/vuforia-engine-package-hosting-for-unity.html

Thank you.

Hello,

Today we’re launching a patch to the Vuforia Engine 8.5 Unity Extension (8.5.9) to include a fix for a linker error seen in Xcode when building Vuforia Engine iOS apps with Unity 2019.3 beta 8 and later. The new version will be made available via Unity’s package manager.

Hello,

We are aware of iOS build failures occurring when using Vuforia Engine 8.5.8 and the latest Unity Editor 2019.3 beta, and we are actively working on resolving the issue with a patch release.

In the meantime, please follow these steps to work around the issue:

Hello,

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.

Thanks,

Vuforia Engine Support

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.

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

to:

#if UNITY_2018

We are aware of the following known issues with Unity 2019.1. These issues have not been observed with Unity 2018.4, so if you're impacted we recommend to stay with that version.

Issues seen with Unity 2019.1.x with Vuforia Engine 8.1.X and 8.3.X:

Update: this has been fixed in Unity 2019.1.4f1

We are currently looking into a known issue where errors like the following are displayed after importing a Vuforia sample from the Asset Store into Unity 2019.1:

Library/PackageCache/com.unity.package-manager-ui@2.0.3/Editor/Sources/UI/PackageDetails.cs(5,32): error CS0234: The type or namespace name 'UIElements' does not exist in the namespace 'UnityEngine.Experimental' (are you missing an assembly reference?)
