Error in the zed-unity plugin

Good day! We created a project to watch videos with depth data from the zed x mini camera on an oculus headset. The zed-unity plugin was used for the project. The version of the zed sdk on the laptop was 5.0.0, and the plug-in was 5.0.1. windows 10. The test build of the project worked by taking video from the stream on the zed box. But after updating the zed sdk to version 5.0.1, the project stopped working, and we can’t make a new version of the application, because the zed-unity plugin requires the previous version of the zed sdk, but it doesn’t accept the new one. Apparently, the conflict arises due to the fact that the zed-unity plugin is not adapted to the zed sdk 5.0.1 update. In addition, we updated the system to Windows 11 while maintaining all installed programs, this apparently does not matter… Please fix the error with the plugin.


I have two Unity projects running on Windows 11, ZED SDK 5.0.1 and Unity Plugin 5.0.1 using the ZED 2i camera and everything is working fine.

I tested the ZED Unity Plugin 5.0.1 on my Unity project running ZED SDK 5.0.0 and it broke it. I had to update the SDK to 5.0.1 all around.

I don’t know if that helps, but I’d try to get get an example project running from scratch using 5.0.1 for both the SDK and Plugin. It should work. Then try and see why the other project isn’t working.

Unfortunately, we broke the binary compatibility between the 5.0.0 and 5.0.1 version of the SDK. That means you have to use the 5.0.1 to be able to run the latest version of the Unity plugin.

But I already mentioned above that I did update the ZED SDK on my computer to 5.0.1! It was after this update that the error appeared, which is shown in the screenshots above! It seems like the ZED Unity plugin ‘doesn’t see’ the updated version on the laptop. The console message suggests updating the ZED SDK version, even though I already have ZED SDK 5.0.1 installed and I’m installing the plugin version 5.0.1 too!

That’s exactly what I did: created a new project, updated the SDK to 5.0.1 on my laptop, and installed the new plugin version 5.0.1 from the Git link - but the same console error pops up as in the screenshot. It’s as if the updated SDK version isn’t being detected. Whereas with version 5.0.0, this problem never occurred

Can you run our diagnostic tool and share the report please?

If you run ZEDfu, do you see V5.0.1 on the bottom right (can see it in the picture)?
