zView AR mode error

Hello,

I am building an application using Unity 2022.3.62f3 with the URP render pipeline and the latest zView / zCore Unity packages. I followed the official guidelines to set up the zView connection and UI controls, but I cannot get AR mode to work.

I have already implemented zView AR mode in other projects where it worked correctly. The only difference in this case is that I am using the URP render pipeline instead of the built-in one.

My application successfully connects to zView, and I can also pause the connection and start/stop/pause recordings. However, as soon as I launch AR mode, the application starts to break. All cameras get disabled, including the zCamera and the zView-instanced virtual cameras, and several errors start appearing (listed below).

Error 1

Failed to find zView AR mode URP scriptable renderer.
UnityEngine.Debug:LogError (object)
zSpace.zView.VirtualCameraAR:FindURPScriptableRendererAndFeatures (bool,int) (at Assets/Plugins/zSpace/zView/Scripts/VirtualCameraAR.cs:521)

zSpace.zView.ZView/<EndOfFrameUpdate>d__74:MoveNext () (at Assets/Plugins/zSpace/zView/Scripts/ZView.cs:1233)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

This error appears even if I include the zView AR mode URP renderer asset in the scriptable render pipeline settings.

Error 2

The screen position values change during runtime depending on the user’s eye tracking, so this error appears very frequently.

Error 3

Failed to render frame.

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

This one is less frequent than Error 2, but still occurs quite often.

I also tried adding dedicated rendering cameras and zView URP cameras, but that did not solve the issue.

I would greatly appreciate any help in identifying or resolving this problem.

Thanks,
Edoardo
