Description

Shader errors are appearing in Play mode in Unity 6000.2.6f2.

These shader errors don't seem like they're affecting functionality. But should still be resolved.

Steps to Reproduce

2. Import Zed SDK plugin. Set your project to use DirectX 11.
3. Create a Scene, disable the Main Camera, add the ZED rig Mono prefab,
4. Enter Play mode
5. Observe console

Expected Result

No shader errors should appear.

I have encountered the same issue. I am running the body tracking sample: https://www.stereolabs.com/docs/unity/body-tracking. and I cannot see any avatar. I don't know if this errors cause the issue.

Sadly, I can't reproduce the issue. Are you using URP/HDRP or SRP ?

Edit: I just saw you were using URP...

[Bvallon-sl]

Ok! It should be fixed now. Can you try to reimport the plugin (v5.1.0)?

Hi Bvallon, thank you very much for your lighting speed fast fixing! Yesterday I switched to old version on Unity 2022.3 LTS and this issue disappear. Not sure if it works with Unity 6 now. I will return to my office on Monday and I have a look. Thanks!

I was am Unity 6000.2.6f2 with zed unity 5.1.0 SDK and Windows Zed 5.1.0 install. I would get the following error by having a simple URP scene. I tried to use the ZED_Rig_Mono prefab with default settings. On play, I would get these sorts of errors:

NullReferenceException: Object reference not set to an instance of an object
ZEDRenderingPlane.SRPStartFrame (UnityEngine.Rendering.ScriptableRenderContext context, UnityEngine.Camera[] rendcam) (at ./Library/PackageCache/com.stereolabs.zed@310631acd842/SDK/Helpers/Scripts/Display/ZEDRenderingPlane.cs:1343)

The zed manager would auto disable itself on runtime. The problem turned out to be that my system was defaulting to Direct3D12. I went into project settings > Other settings > unchecked "auto graphics API for windows" and changed the order so Direct3D11 is first. Now things run fine! I'm not quite sure why that fixes it for me.

The plugin is not compatible with DX12 and it is now the default for Unity 6 and newer. I'll take a look at why the plugin did not simply return an error as it should have.
