[Error] [omni.usd._impl.utils] Failed to open crate file ./Modern.usd:

Omniverse Core Platform Kit App Template / SDK

I am working in USD Composer launched with the Kit-App-Template, using a Local Nucleus Server.

When I create an Xform Prim and try to add References, the following error occurs and the reference is not added.

[Error] [omni.usd.impl.utils] Failed to open crate file ./Modern.usd:

Hi and there and welcome. Can you provide some more details please.

  1. What version of Kit? 106? 107?
  2. Can you open a normal demo file in USD Composer, like the astronaut etc?
  3. Are you trying to open the file through the USD Composer menu system, File > Open, or the Content Browser, or are you trying through code?
  4. You are trying to add references underneath a Xform? How exactly are you doing that? That is really not the way. If you want to add a reference to “modern.usd”, you can just drag it into the viewport or the Stage Tree and it will import. I would just try to directly add it under an Xform. Try that method first and see if it works well.
  5. When you try to open Modern.usd, does it open normally?

Thank you for your response!

  1. Kit SDK Version: 107.2.0+feature.190796.ae1b1071.gl
  2. It works well.
  3. I’m using the Content Browser.
  4. I’ve added a video demonstrating the approach I’m trying to take. Specifically, when I use drag and drop into the viewport or Stage Tree, the assets are loaded correctly using the Payloads method. However, when I click “Convert Payloads to References” in the Stage Tree, an error occurs.
  5. It opens without any issues.


I also have a question regarding the “Select Mode” on the left bar of the Viewport in USD Composer.

For example, when I open the astronaut demo file and choose “Select Mode → All Model Kinds”, then click on the astronaut object in the Viewport, the entire model gets selected, and I can move it as a whole — as expected. On the other hand, if I select “Select Mode → All Prim Types” and click on the astronaut, I understand that only a part of the model should be selected.

However, in my case, only parts of the model are selected regardless of which of the two selection modes I use.
