Hi,

Are you using Ubuntu?

Can you go at the location of the dll, run

ldd libsl_unitywrapper.so

and send me the output please?

It should be located in your Unity project, in /Library/PackageCache/com.stereolabs.zed/SDK/Plugins/linux

Yes, I am using Ubuntu 20.04.6 LTS.

ok then, can you run :
sudo apt-get install libusb-dev libusb-0.1-4

It should solve your problem

Thanks, that fixed most of the errors.
Unfortunately I still get the following error:

Are you using URP?

I think you did not set URP as the active render pipeline.

Can you make sure to follow all these steps ?

Yes, I did use URP and have followed all these steps. However, I was able to get it to work with HDRP :slight_smile:
Thanks for your help!
