Unity 2019 LTS Vuforia + Cardboard iOS Issue

By joaoborks on Fri, 10/09/2020 - 21:00

Hi,

I've been using Unity 2019.4.11f1 and Google Cardboard 1.2.0 with no major issues. I've managed to integrate Vuforia 9.4.6 on Android, but not on iOS. If I have the Vuforia package, the cardboard VR will not start and otherwise, it will work normally.

So both Vuforia and Google Cardboard are vital to our app, and we need to find a way to make them work together on iOS. I figure it must be something specific, but I can't tell for sure.

The logs aren't very meaningful:

[Subsystems] Loading plugin cardboard_api for subsystem Display...
[Subsystems] Failed to initialize subsystem Display [error: 1]
[Subsystems] Loading plugin cardboard_api for subsystem Input...
[Subsystems] Failed to initialize subsystem Input [error: 1]

Anyways, we have a thread on the official cardboard repository as well. I don't know which package is causing the issues.

I've created a repository to

I've created a repository to reproduce the problem containing only the Cardboard VR Sample scene and Vuforia binaries.

Same happens to me, can't use

Same happens to me, can't use vuforia with google cardboad on Unity 2019, that's devastating, because we have a project that already uses both and we can't upgrade it since ios 14.0.1 came out.

We're having the same issue.

We're having the same issue. This is a critical issue for us that leaves the app unusable on iOS.

I just found out that Vuforia

I just found out that Vuforia selects Open GL ES 3.x instead of Open GL 2.x, and that's probably why the VR is not loading (even though I only have Open GL ES2 on my player settings):

It's been 2 weeks since I

It's been more than 2 weeks since I first reported this and nobody from Vuforia responded. This issue is affecting my app release since iOS 14 came out. I cannot upgrade my app or publish new features due to this particular issue with iOS.

@mcotora Any advice?

Hi,

Based on your input, the issue is with Vuforia not selecting openGLES 2 on iOS. Unfortunately this is as expected as we do support only openGLES 3+ on iOS.

Supported versions: https://library.vuforia.com/content/vuforia-library/en/platform-support/supported-versions.html

Thank you for your response

Thank you for your response @mcotora. I've totally missed that Graphics API Support page.

I have updates

Having exactly the same issue here.

Have a Unity project with Cardboard + Vuforia on Android and iOS that was working just fine until not long ago.

It's been almost 2 months

It's been almost 2 months since iOS 14 came out, and we still cannot update our apps only because of this issue. I don't know what else to try, but I think we as users can only go so far. We need developer assistance on this issue.

Today, Google Cardboard has

Today, Google Cardboard has released its 1.4.0 version with official support to OpenGL ES 3. Vuforia still doesn't work. I hardly have any hope now.

iOS build log:

Damm even I am having a similar kind of issue, I have searched all over the internet and even have posted on number of threads on different forum, no solution seems to work. I am really frustrated, can anyone of you here help me resolve this issue, I am very much tired now.
