Solaris is Houdini’s environment for layout, lookdev and lighting and is built on USD, the open source Universal Scene Description format created by PIXAR. This makes Solaris a great environment for interacting and authoring USD scenes and assets. USD is an optimized system for organizing your assets that allows for efficient workflows for teams or individuals.

In this course, you will continue the conversation about what USD is, and how you author it using Solaris. Some of the topics that will be covered include: bringing USD files into Solaris, how to work with USD layers, and an analysis of what is happening inside of USD files. The goal for this course is to build a strong foundation of USD concepts in Solaris in order for you to be able to build scenes and workflows.

    Truly awesome to see more USD/Solaris content. Looking forward to seeing advanced USD stuff as well.

    Hi again Peter, get same problem here with #2 "Sublayer & Reference" section
    Get errors on the Reference node:
    Error Unable to find layer file: -
    Warning Fixed invalid USD path: /_
    Works only with previous "reference" node asset, and don't understand /`@soucename` variable, only with hardcoded /simple_scene

      I have exactly the same problem. Any advice? Thx.

        could be an error with name spacing, I had a space in the name of the folder my hip file was in and it worked after I changed it?

        • derek_lindell 2 years, 8 months ago  | 

          or could be the fact you're using houdini non-commercial which means it generates .usdnc files instead of .usda files!

      The issue is that some of the output paths on the ROPs should be using $HIPNAME, but they're not.

      All paths should be starting with $HIP/usd/$HIPNAME/

    as said before , this is Truly awesome.

    this is a great intro, thanks for taking the time to create

    I re-downloaded this recently and it seems to work fine out of the box now, so it must have been fixed.

    Hello, I'm a beginner at Hoodini. Sublayer & Reference Import -> C:/Users/hskwak/Desktop/Houdini/Solaris_Tuto_preset/usd/USD_with_Solaris_Authoring/scenes/simple_scene.usd path, but no files are called in because the folder has been created up to screens. Do I need to export usd individually? - Automatic translation is being used

    the hip file link seems expired, can anyone share it THX

    Thanks for the thorough dive! Perhaps this tutorial is a little outdated now, i've been following along and learning quite a bit still. Working in apprentice so re-naming my paths to ...nc for now which has been working. I'm at the Analyzing Instancing part and i am not seeing the materials change to green in any of the cases while looking in Karma XPU mode but i do see it function in Karma CPU mode. Just curious what the difference is there, or if something needs to be set in a karma settings node or something to get parity. ( way out of my league re: karma/rendering stuff mostly just curious, my main interest is in asset creation and layout, less rendering atm). Thanks!

      This seems like a bug to me, since I believe it worked when I created this course. Could you submit a bug about this please?
