    what editor are you running on? I am on 2020.3.27f1c1. I was wondering if I can run this plug-in tool on 2021.1.28f1. However, The USD plug-in does not show on the package manager, are you experiencing the same problem as well?

    Hey,
    We make sure to properly initialize the system path before loading USD and it worked so far but it really looks like a library version clash. Do you have any USD versions installed locally on your machine or did you try replacing the USD binary inside the package?
    I just tried it in 2021.2.8 with a local install of 22.03 in my system path but it loaded just fine. I will do another test in 2020.3 but I really suspect a system config thing we didn't catch before.

    Hello,
    No, not really, I don't know what is the problem here, I have never installed the USD package before. All I did was followed the instruction and download the latest version of the package 3.0.0 (as shown in the picture) . All the installations are fine. However, when I tried to import the USD it shows the error. I am currently runing on the 2020.3.27f1c1 editor and I could't find the package on 2021.1.28f1 editor. If you can, can you please provide me a link to download the package, so I can have the package install locally? Do you think that might work?

    Looking forward to your replly.

    Regards

    In Unity 2021, experimental packages are not listed in the package manager. You can install by name, by git URL or by copying the USD entry in the package manifest from your old project.
    See here https://forum.unity.com/threads/usd-for-unity-updates.646645/page-5#post-7993902 for installation instructions.
    Let me know if it works for you in 2021.1.

    For your issue in 2020.3, can you give me a list of your installed packages?
    Also did you happen to bake GI with Enlighten before loading USD? Both USD and Enlighten uses TBB and there might a version clash there.

    Another USD package could indeed cause this issue, for example if the PiXYZ USD package is installed along side the USD Unity SDK - they internally use different native builds of USD and I believe they could potentially cause this issue if both are loaded into the editor process.
