Topic Description

Detailed Description

I’m experiencing a repeated issue related to missing or unreadable texture files when launching or using certain assets in Isaac Sim (v4.2.0). I was trying to load the Robotiq 2F-140 gripper asset and the Office environment from the default Isaac assets directory via Omniverse Nucleus.

I expected the textures and environments to load normally, but instead received multiple error messages indicating texture loading failures and unsupported operations. As a result, UI thumbnails are missing, and environment checkpoints cannot be retrieved.

Steps to Reproduce

  1. Launch Isaac Sim 4.2.0
  2. Open or import the office USD file
  3. Try to load the Office environment from:
    omniverse://localhost/NVIDIA/Assets/Isaac/4.5/Isaac/Environments/Office/office.usd

Additional Information

What I’ve Tried

  • Restarted Isaac Sim and reloaded the assets
  • Verified internet connection in case the issue was with CDN delivery
  • Attempted to manually re-import the asset via the Content Browser
  • Checked Nucleus server access; other assets load without issues

Related Issues

I have not found an identical post, but similar texture loading errors have been mentioned in Omniverse forums.

@aiden_kim i see you marked both 4.5.0 as well as 4.2.0. are you also experiencing the texture loading issue in both or limited to the latter?

3

It’s happening in both versions. The loading time is too long, and I can’t access Nucleus.

4

I tested opening the office.usd file using the “Isaac Sim Asset Browser [Beta]” on Ubuntu, and it loaded successfully without any errors. Could you confirm if the PNG files mentioned in your error logs are accessible on your system?

I was able to resolve the issue by manually adding the assets.

According to the following documentation:

Local Assets Packs
Isaac Sim Local Assets Packs are available to be used locally and in an air-gapped environment. For version 4.5.0, the total assets are divided into three separate packs. All three are required for local use.

Thank you for your support!
