Unreal Engine will not export USD

Omniverse Connections & Data Exchange Omniverse Connectors

I have my scene and then go to export all following this tutorial (https://www.youtube.com/watch?v=IgQNr-zWf0w&ab_channel=LightcraftTechnology)

When I go to export all, I get this error in my output log
LogOmniverseUsd: Warning: USD Error in pxrInternal_v0_23__pxrReserved__::anonymous-namespace'::_GetPluginForType at line 147 in file C:\USD_src\pxr\usd\ar\resolver.cpp : Failed to find plugin for ArDefaultResolver LogOmniverseUsd: Warning: USD Error in pxrInternal_v0_23__pxrReserved__::anonymous-namespace’::GetAvailablePrimaryResolvers at line 307 in file C:\USD_src\pxr\usd\ar\resolver.cpp : Failed verification: ’ availablePrimaryResolvers.back().type == defaultResolverType ’

What am I missing here?

by the output, I am assuming it has something to do with the plugin “ArDefaultResolver”. Anyone have an idea on how to fix this?

I’m not exactly sure what’s happening here, but I have a couple ideas:

  • Make sure that you’re exporting the .usd file extension type. Your warning log indicates something about UsdzResolver, and I’m not sure why it says that.
  • I wonder if your Omniverse USD Resolver isn’t initialized correctly, and the only reason I can think that would be an issue is because there was an issue with your installation. Perhaps an uninstall/reinstall through the Omniverse Launcher might helpl?
  • You do not indicate what version of the Unreal Editor and Connector you are running. You can get the Connector version by going to the Omniverse button and selecting About Plugin
