Complie error on windows: VS2022+WIN22H2

[lyd405121]

I found a compile error and sovle it

• I build usd with build_usd.py as the readme said, but failed:

How to sovle it

• Modify the cmake build command in build_usd.py at line 445
• From Run("cmake --build . --config {config} --target install -- {multiproc}"
• To Run("cmake --build . --config {config} --target install --parallel {multiproc}"

More tips

• If you find download process failed, you can manually download those zip or tar.gz and copy to destination file

Background

• We deside to migrate our scene description scheme to usd
• And we found usd is really flexible format and many software has their usd importer
• We have tried UE4 UNITY blender houdini and so on，But has some questions.

Question

• Those software has their standard or extension for usd，which lead different software‘s output usd file not compatible
• For example we use ue4 export a usd file with animation to nvidia omniverse，the morph animation lost, but gltf file is complete.
• So the question is

  Will usd be more strict standard in the future like the gltf standard does?

@lyd405121 Could you also provide this information?

• which branch or tag are you building?
• what was your build_usd.py command line?

On your Questions ~ a great place to ask them would be on the ASWF Slack (https://join.slack.com/t/academysoftwarefdn/shared_invite/zt-1ojp8pwdg-T8~QQpD982JkfJD_0nulig). There you will find a channel named #wg-usd-games. The people there may already know the answer to your export questions.

In terms of stricter standards, that will happen over time, for sure. The first question though, would be to find out whether the ue export is working as you expect, and then if the import to omniverse works as you expect. With or without standards, it's good to let vendors know what features you need from their implementation, such as morph animations.

FYI

• Release branch,latest version

• My cmd just as the readme said

  python build_scripts\build_usd.py ".\deps"

• Maybe specific VS(2022 17.4.4) or cmake(3.25.2) version will get such result

• I just share my change of the script, helping others have same problem

• USD is really a good thing for 3D industry

More

• ASWF? Is that mean usd will be maintained by Academy Software in the future？
• Thanks for your kind words, I will walk round the channel looking for some master piece

ASWF is helping with the USD effort by organizing forums and community. Although the ASWF hosts many projects in the same domain, such as MaterialX, OpenEXR, and so on, there's no plans for it to also take on USD. ASWF is however a place where developers with similar interests spend a lot of time :)
