    Hi !

    The current released USD plugin is experimental that's why you don't see it in the Package Manager.
    To get it, in the package manager, select the "+" icon on the top left, select "add package by name" and enter: com.unity.formats.usd

    This will get you USD 3.0.0-exp.2.

    Yeah this advice isn't in line with unity's blog posts and docs on the subject (for example here or here). As I always say, guys it really, really sucks every time I have to find a random forum post to figure out how to use Unity in some way because your docs are wrong or incomplete.

    Hi @bfoddy

    The documentation you link to is valid for the versions of Unity to which they refer. Starting with Unity 2021.1, the new Package lifecycle removes the "Preview" state for packages. As of 2021.1, the USD package is now "Experimental". Experimental packages are governed by different rules than the previous "Preview" packages. You can read more about the differences here: https://docs.unity3d.com/Manual/pack-exp.html

    As this is the AR forum i wonder why nobody mentioned the obvious huge pitfall regarding USD and unity
    Why is'nt there any runtime support on iOS or Android for the USD package

    This is a serious oversight, considering the whole iOS ARKit/Scenekit stuff is literally build arround usd

    Hi @spacefrog,

    While I'm unable to directly answer your question, Unity and Weta have been involved with the USD working group for some time now.

    The USD working group is a public and open collaborative community if you want to follow the latest USD news. The most recent meeting minutes at time of writing are available at this link: https://wiki.aswf.io/display/WGUSD/January+18th,+2023.
