LightshipOcclusionExtension is not yet supported in combination with ar foundation version 6.0 or later

I'm Stuck
1

Include the following details (edit as applicable):

  • Issue category: Unity Example Package
  • Device type & OS version: Editor
  • Host machine & OS version: Mac
  • Issue Environment : Editor
  • Xcode version:
  • ARDK version: 3.15.0-2508040839
  • Unity version: 6000.0.53f1

Description of the issue:

In the ardk-samples, in the Occlusion scene, the LightshipOcclusionExtension has a message stating “This Component is not yet supported in combination with ar foundation version 6.0 or later.” I’m using AR Foundation 6.0.6

Also, in the Package Manager, it states that Niantic Lightship AR Plugin is in pre-release. But I can’t figure out how to install a released version.

Any tips?

Hi David,

Thank you for reaching out!

We are aware of issues with AR Foundation 6.0 and later with ARDK 3.15. In order to have the best experience – even on Unity 6 – we recommend using AR Foundation 5.2.0. Please downgrade to that version via the Package Manager and follow up with your experience.

Regarding the “pre-release” message: The version of the ARDK you’re using is the latest available and you can safely ignore that message.

Let me know if you have any other questions or need further clarification!

Kind regards,
Maverick L.

Thank you for your response. My understanding is that AR Foundation 5.2.0 doesn’t support Unity 6, is that true? If Unity 6 is supported, I don’t see how I can downgrade AR Foundation in Unity 6’s Package Manager

When I downloaded the Lightship example at GitHub - niantic-lightship/ardk-samples: ARDK Samples Unity Project , the project is in Unity 6.

In the “Sample Projects” doc ( Sample Projects | Niantic Spatial Platform ) the language implies that I can use Unity 6 or 2022.3.62f1.

So I’m a little unclear. Can I use Unity 6 and downgrade to AR Foundation 5.2.0? Or do I have to use Unity 2022.3.62f1 so I can use AR Foundation 5.2.0?

In the “Setting Up the Niantic SDK for Unity” doc ( Setting Up the Niantic SDK for Unity | Niantic Spatial Platform ) it states that Unity 6 is supported.

You’re very welcome.

Yes, the ARDK supports both Unity 6 and Unity 2022, but there’s a known incompatibility between AR Foundation 6.0 and ARDK 3.15. In our tests, AR Foundation 5.2.0, ARDK 3.15, and Unity 6 work as expected together. You should be able to downgrade and maintain your project in Unity 6.

Kind regards,
Maverick L.

Thank you for that clarification! Do you have a resource you can share for downgrading AR Foundation to 5.2 in Unity 6? I can not find a way to do this using the Package Manager. Thank you!

After researching, I’ve discovered that it is not possible to use AR Foundation 5.2 in Unity 6. This was confirmed by a member of the AR Foundation team → How to downgrade to AR Foundation to 5.2 in Unity 6? - #7 by andyb-unity - Unity Engine - Unity Discussions
